commit 400dedb1d0758e1d2931eb99aee896cd33a5a574
Author: Zack Weinberg <zackw@panix.com>
Date: Sun Nov 20 23:00:02 2016 -0500
The bits/types/*.h treatment for stdio and wchar.
wint_t is a little finicky because it might be defined by stddef.h, which
belongs to the compiler.
In addition to the _types_, a bunch of other declarations shared between
wctype.h and wchar.h are factored out to their own header.
* libio/bits/types/FILE.h, libio/bits/types/__FILE.h
* wcsmbs/bits/types/mbstate_t.h, wcsmbs/bits/types/__mbstate_t.h
* wcsmbs/bits/types/wint_t.h: New single-type definition files.
* wctype/bits/wctype-wchar.h: New file holding declarations shared
between wctype.h and wchar.h.
* libio/Makefile, wcsmbs/Makefile, wctype/Makefile:
Install them.
* include/bits/types/FILE.h, include/bits/types/__FILE.h
* include/bits/types/mbstate_t.h, include/bits/types/__mbstate_t.h
* include/bits/types/wint_t.h, include/bits/wcsmbs-wchar.h:
New wrappers.
* include/stdio.h, include/wchar.h, include/wctype.h:
No need to handle __need macros.
* grp/grp.h, gshadow/gshadow.h, hurd/hurd.h, iconv/gconv.h
* libio/stdio.h, mach/mach.h, misc/mntent.h, pwd/pwd.h
* shadow/shadow.h, stdio-common/printf.h, wcsmbs/uchar.h
* wcsmbs/wchar.h, wctype/wctype.h
* sysdeps/generic/_G_config.h, sysdeps/unix/sysv/linux/_G_config.h
Use the new files instead of __need macros.

Author: Zack Weinberg <zackw@panix.com>
Date: Wed Nov 16 16:20:26 2016 -0500
Clean up redundancies between string.h and strings.h.
* string/string.h [__USE_MISC]: Include strings.h.
(__bzero, bcmp, bcopy, bzero, index, rindex)
(strcasecmp, strncasecmp, strcasecmp_l, strncasecmp_l)
(ffs, ffsl, ffsll): Don't declare.
* string/strings.h: Do not suppress the file if string.h has
already been included.
(bcmp, bcopy, bzero, strcasecmp, strncasecmp): Add __nonnull
annotations.
(index, rindex): Define inline forwarders even if
__CORRECT_ISO_CPP_STRING_H_PROTO is defined.
(ffs): Use __attribute_const__.
(ffsl, ffsll): Declare here.
(strcasecmp_l, strncasecmp_l): Correct comments; these functions
have now been standardized.
* include/string.h (__bzero): Declare here.

commit 18fc1abd684220501b18fad91236499e0787dbec
Author: Zack Weinberg <zackw@panix.com>
Date: Mon Nov 21 08:16:27 2016 -0500
Clean up conditionals for declaration of gets().
gets() has the dubious honor of being the only C89 library feature
that has been completely removed from the current C and C++ standards.
glibc follows suit by not declaring it in _GNU_SOURCE mode either, but
it remains present in older compatibility modes. Internally, two test
cases need to see stdio.h make the declaration, but all our internal
code is of course compiled under _GNU_SOURCE. This is currently
kludged by duplicating the gets declaration, fortify wrapper and all,
in include/stdio.h. Also, the conditional in the public headers for
deciding when to declare gets is complicated and repeated in two places.
This patch adds a new macro to features.h that encapsulates the
complicated rule for when to declare gets. stdio.h and bits/stdio2.h
can simply test __GLIBC_USE (DEPRECATED_GETS). Then, instead of
having a duplicate gets declaration in include/stdio.h,
debug/tst-chk1.c and stdio-common/tst-gets.c force that flag on.
* include/features.h (__GLIBC_USE_DEPRECATED_GETS): New macro.
* libio/stdio.h, libio/bits/stdio2.h: Condition gets on
__GLIBC_USE (DEPRECATED_GETS). Update comments to indicate
gets was removed from C++ in C++14.
* include/stdio.h [!_ISOMAC]: Force gets to be declared by
libio/stdio.h, instead of repeating its declaration.
* debug/tst-chk1.c, stdio-common/tst-gets.c: Force gets to
be declared, since we are testing it.
* stdio-common/Makefile (tst-gets.c): Compile with
-Wno-deprecated-declarations.
* debug/Makefile (tst-chk1.c, tst-chk2.c, tst-chk3.c, tst-chk4.cc)
(tst-chk5.cc, tst-chk6.cc, tst-lfschk1.c, tst-lfschk2.c)
(tst-lfschk3.c, tst-lfschk4.cc, tst-lfschk5.cc, tst-lfschk6.cc):
Compile with -Wno-deprecated-declarations.

Always suppress libc-internal declarations for C++ code.
C++ is only used for tests, and some of the internal declarations are
not C++-safe. Rather than playing whack-a-mole with problems, just
turn on _ISOMAC mode for all C++ code.
* include/libc-symbols.h: Define _ISOMAC when __cplusplus is defined.
* include/errno.h, include/stdio.h, include/stdlib.h
* include/time.h, include/unistd.h, include/wchar.h: No need to
check __cplusplus nor use __BEGIN_DECLS/__END_DECLS.
