  86 *** Major changes in newlib version 1.8.2:
  87
  88 * RTEMS features and fixes from Joel Sherrill.
  89
  90 * More work on reentrant routines.
  91
  92 * Floating point math library check, --enable-newlib-hw-fp.
  93
  94 *** Major changes in newlib version 1.8.1:
  95
  96 * Added check for --enable-newlib-mb configure option which defines the
  97   MB_CAPABLE macro.  Multibyte support for JIS, SJIS, and EUC-JP implemented.
  98
  99 * Reduced code size for libm modules.
 100
 101 * Replaced the BSD malloc with Doug Lea's malloc.
 102
 103 *** Major changes in newlib version 1.8.0:
 104
 105 * Added simulated signal handling functions _raise_r, _signal_r, raise, and
 106   signal except for sparc-sun-sunos*, i[3456]86-*-sco*, and a29k-*-* systems,
 107   which already provide access to signal.  The signal functionality provided
 108   does not interact with hardware generated signals.
 109
 110 * Added reentrant function rand_r from POSIX.1c.
 111
 112 * Removed _asctime, _next, _scanpoint, and _signgam fields from struct
 113   _reent.  These are no longer necessary since there are now functions
 114   that explictly support multiple threads (asctime_r, ctime_r, gamma_r,
 115   gmtime_r, lgamma_r, localtime_r, rand_r, & strtok_r).
 116
 117
 118 *** Major changes in newlib version 1.7.0:
 119
 120 * Cross compiler target libraries are now built in a subdir of the top level
 121   build directory.
 122
 123   Old way: build
 124                 /newlib
 125                        /m68020
 126                               /m68881
 127   New way:
 128            build
 129                 /m68k-coff
 130                           /m68020
 131                                  /m68881
 132
 133   where m68020 and m68881 are multilib subdirectories
 134
 135 * m68k targets support --disable options to avoid building unwanted versions
 136   of the libraries.
 137
 138   --disable-softfloat - don't build libc, libg++, etc. for -msoft-float
 139   --disable-m68881    - don't build libc, libg++, etc. for -m68881
 140   --disable-m68000    - don't build libc, libg++, etc. for -m68000
 141   --disable-m68020    - don't build libc, libg++, etc. for -m68020
 142
 143   These options have *no* effect on the default libraries, so if the default
 144   is -m68020, --disable-m68020 is nilpotent.
 145
 146 * Reentrancy support in libm removed.
 147
 148 * strtok, strtol, strtoul, assert, div, ldiv, qsort, vfprintf
 149   replaced with NetBSD versions.
 150
 151 * Support for systems with 32 bit "doubles" added.
 152
 153 * unctrl added.
 154
 155 * dtoa.c updated from master dtoa.c soruces (netlib.att.com)
 156
 157 * Various bug fixes.
 158
 159 *** Major changes in newlib version 1.6.1:
 160
 161 * Added reentrant functions (asctime_r, ctime_r, gmtime_r, localtime_r,
 162 and strtok_r) from POSIX.1c.
 163
 164 * Removed _asctime_r and _strtok_r functions.
