-	    List of known bugs (certainly very incomplete)
-	    ----------------------------------------------
-
-Time-stamp: <2007-10-27 18:37:51 drepper>
-
-This following list contains those bugs which I'm aware of.  Please
-make sure that bugs you report are not listed here.  If you can fix one
-of these bugs/limitations I'll certainly be glad to receive a patch.
-
-Another source of information about bugs is the problem data base of the
-GNU project.  There is an easy to use WWW interface available at
-
-       http://sourceware.org/bugzilla/
-
-I would appreciate it very much if you could verify the problem was
-not reported before by looking through the database. Before reporting
-a bug please check the FAQ since it discusses also a lot of
-problematic situations.
-
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Severity: [  *] to [***]
-
-[ **]  Closing shared objects in statically linked binaries most of the
-       times leads to crashes during the dlopen().  Hard to fix.
-
-[ **]  The RPC code is not 64 bit clean.  This is getting slowly fixed
-       but expect incompatible changes on 64 bit platforms like Alpha.
-
-[  *]  The precision of the `sinhl' and/or `asinhl' function do not seem
-       to be the best.
-
-[  *]  On Linux, there should be a way to prevent defining the symbol
-       NGROUPS_MAX in the <linux/limits.h> header file.  In glibc it
-       is defined in <posix1_lim.h> which must not make the other
-       symbols in <linux/limits.h> available.
-       [PR libc/140]
-
-[  *]  The libm-ieee `gamma' function gives wrong results (at least for
-       -0.5).
-
-[  *]  The libm-ieee `scalb' function gives wrong results for
-       non-integral second parameters.
-
-[  *]  Several (most?) collation specifications are broken.  The code which
-       is currently there is in most cases inherited from the originial
-       author (in case there is a LC_COLLATE specification in the locale
-       file) or is defined using the default (if iso14651_t1 is included).
-
-       In any case we are missing information to correct the specification.
-       If you find the specification for your language be faulty please
-       send a report with instruction on what to fix.  You don't have to
-       fix the specification yourself.
-
-       The way it finally should look like (if the generic specification
-       is not correct) can be seen in the sv_SE file.  Quite a few changes
-       on top of the generic specification can be made without duplication
-       of the whole LC_COLLATE description.
-
-[  *]  Some of the functions which also handled IPv6 are currently broken.
-       IPv6 and IPv4 lookups occasionally happen when not needed.  This
-       happens in getaddrinfo() and getnameinfo().  IPv4 handling of
-       these functions is OK though and there are patches available to fix
-       the IPv6 code as well.

-Conformance of the GNU libc with various standards
-==================================================
-
-The GNU libc is designed to be conformant with existing standard as
-far as possible.  To ensure this I've run various tests.  The results
-are presented here.
-
-
-Open Group's hdrchk
-===================
-
-The hdrchk test suite is available from the Open Group at
-
-	ftp://ftp.rdg.opengroup.org/pub/unsupported/stdtools/hdrchk/
-
-I've last run the suite on 2004-04-17 on a Linux/x86 system running
-a Fedora Core 2 test 2 + updates with the following results [*]:
-
-	FIPS		No reported problems
-
-	POSIX90		No reported problems
-
-	XPG3		Prototypes are now in the correct header file
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-*** Starting unistd.h
-Missing: extern char *  cuserid();
-Missing: extern int     rename();
-*** Completed unistd.h
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-	XPG4		Prototype is now in the correct header file
-			and the _POSIX2_C_VERSION symbol has been removed
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-*** Starting unistd.h
-Missing: extern char *  cuserid();
-Missing: #define        _POSIX2_C_VERSION       (-1L)
-*** Completed unistd.h
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-	POSIX96		Prototype moved
-			(using "base realtime threads" subsets)
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-*** Starting unistd.h
-Missing: extern int     pthread_atfork();
-*** Completed unistd.h
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-	UNIX98		Prototypes moved and _POSIX2_C_VERSION removed
-			(using "base realtime threads mse lfs" subset)
-
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-*** Starting unistd.h
-Missing: extern char *  cuserid();
-Missing: #define        _POSIX2_C_VERSION       (-1L)
-Missing: extern int     pthread_atfork();
-*** Completed unistd.h
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-
-That means all the reported issues are due to the headers having been
-cleaned up for recent POSIX/Unix specification versions.  Duplicated
-prototypes have been removed and obsolete symbols have been removed.
-Which means that as far as the tests performed by the script go, the
-headers files comply to the current POSIX/Unix specification.
-
-
-[*] Since the scripts are not clever enough for the way gcc handles
-include files (namely, putting some of them in gcc-local directory) I
-copied over the iso646.h, float.h, and stddef.h headers and ignored the
-problems resulting from the split limits.h file).
-
-
-Technical C standards conformance issues in glibc
-=================================================
-
-If you compile programs against glibc with __STRICT_ANSI__ defined
-(as, for example, by gcc -ansi, gcc -std=c89, gcc -std=iso1990:199409
-or gcc -std=c99), and use only the headers specified by the version of
-the C standard chosen, glibc will attempt to conform to that version
-of the C standard (as indicated by __STDC_VERSION__):
-
-GCC options		Standard version
--ansi			ISO/IEC 9899:1990
--std=c89		ISO/IEC 9899:1990
--std=iso9899:199409	ISO/IEC 9899:1990 as amended by Amd.1:1995
--std=c99		ISO/IEC 9899:1999
-
-(Note that -std=c99 is not available in GCC 2.95.2, and that no
-version of GCC presently existing implements the full C99 standard.)
-
-You may then define additional feature test macros to enable the
-features from other standards, and use the headers defined in those
-standards (for example, defining _POSIX_C_SOURCE to be 199506L to
-enable features from ISO/IEC 9945-1:1996).
-
-There are some technical ways in which glibc is known not to conform
-to the supported versions of the C standard, as detailed below.  Some
-of these relate to defects in the standard that are expected to be
-fixed, or to compiler limitations.
-
-
-Defects in the C99 standard
-===========================
-
-Some defects in C99 were corrected in Technical Corrigendum 1 to that
-standard.  glibc follows the corrected specification.
-
-
-Implementation of library functions
-===================================
-
-The implementation of some library functions does not fully follow the
-standard specification:
-
-C99 added additional forms of floating point constants (hexadecimal
-constants, NaNs and infinities) to be recognised by strtod() and
-scanf().  The effect is to change the behavior of some strictly
-conforming C90 programs; glibc implements the C99 versions only
-irrespective of the standard version selected.
-
-C99 added %a as another scanf format specifier for floating point
-values.  This conflicts with the glibc extension where %as, %a[ and
-%aS mean to allocate the string for the data read.  A strictly
-conforming C99 program using %as, %a[ or %aS in a scanf format string
-will misbehave under glibc if it does not include <stdio.h> and
-instead declares scanf itself; if it gets the declaration of scanf
-from <stdio.h>, it will use a C99-conforming version.
-
-
-Compiler limitations
-====================
-
-The macros __STDC_IEC_559__, __STDC_IEC_559_COMPLEX__ and
-__STDC_ISO_10646__ are properly supposed to be constant throughout the
-translation unit (before and after any library headers are included).
-However, they mainly relate to library features, and GCC only knows to
-preinclude <stdc-predef.h> to get their definitions in version 4.8 and
-later.  Programs that test them before including any standard headers
-may misbehave with older compilers.
-
-GCC doesn't support the optional imaginary types.  Nor does it
-understand the keyword _Complex before GCC 3.0.  This has the
-corresponding impact on the relevant headers.
-
-glibc's <tgmath.h> implementation is arcane but thought to work
-correctly; a clean and comprehensible version requires compiler
-builtins.
-
-For most of the headers required of freestanding implementations,
-glibc relies on GCC to provide correct versions.  (At present, glibc
-provides <stdint.h>, and GCC doesn't before version 4.5.)
-
-The definition of math_errhandling conforms so long as no translation
-unit using math_errhandling is compiled with -fno-math-errno,
--fno-trapping-math or options such as -ffast-math that imply these
-options.  math_errhandling is only conditionally defined depending on
-__FAST_MATH__; the compiler does not provide the information needed
-for more exact definitions based on settings of -fno-math-errno and
--fno-trapping-math, possibly for only some source files in a program.
-
-
-Issues with headers
-===================
-
-None known.
