 324
 325 * More work on reentrant routines.
 326
 327 * Floating point math library check, --enable-newlib-hw-fp.
 328
 329 *** Major changes in newlib version 1.8.1:
 330
 331 * Added check for --enable-newlib-mb configure option which defines the
 332   MB_CAPABLE macro.  Multibyte support for JIS, SJIS, and EUC-JP implemented.
 333
 334 * Reduced code size for libm modules.
 335
 336 * Replaced the BSD malloc with Doug Lea's malloc.
 337
 338 *** Major changes in newlib version 1.8.0:
 339
 340 * Added simulated signal handling functions _raise_r, _signal_r, raise, and
 341   signal except for sparc-sun-sunos*, i[3456]86-*-sco*, and a29k-*-* systems,
 342   which already provide access to signal.  The signal functionality provided
 343   does not interact with hardware generated signals.

 346
 347 * Removed _asctime, _next, _scanpoint, and _signgam fields from struct
 348   _reent.  These are no longer necessary since there are now functions
 349   that explictly support multiple threads (asctime_r, ctime_r, gamma_r,
 350   gmtime_r, lgamma_r, localtime_r, rand_r, & strtok_r).
 351
 352
 353 *** Major changes in newlib version 1.7.0:
 354
 355 * Cross compiler target libraries are now built in a subdir of the top level
 356   build directory.
 357
 358   Old way: build
 359                 /newlib
 360                        /m68020
 361                               /m68881
 362   New way:
 363            build
 364                 /m68k-coff
 365                           /m68020
 366                                  /m68881
 367
 368   where m68020 and m68881 are multilib subdirectories
 369
 370 * m68k targets support --disable options to avoid building unwanted versions
 371   of the libraries.
 372
 373   --disable-softfloat - don't build libc, libg++, etc. for -msoft-float
 374   --disable-m68881    - don't build libc, libg++, etc. for -m68881
 375   --disable-m68000    - don't build libc, libg++, etc. for -m68000
 376   --disable-m68020    - don't build libc, libg++, etc. for -m68020
 377
 378   These options have *no* effect on the default libraries, so if the default
 379   is -m68020, --disable-m68020 is nilpotent.
 380
 381 * Reentrancy support in libm removed.
 382
 383 * strtok, strtol, strtoul, assert, div, ldiv, qsort, vfprintf
 384   replaced with NetBSD versions.
 385
 386 * Support for systems with 32 bit "doubles" added.
 387
 388 * unctrl added.
 389
 390 * dtoa.c updated from master dtoa.c soruces (netlib.att.com)
 391
 392 * Various bug fixes.
 393
 394 *** Major changes in newlib version 1.6.1:
 395
 396 * Added reentrant functions (asctime_r, ctime_r, gmtime_r, localtime_r,
 397 and strtok_r) from POSIX.1c.
 398
 399 * Removed _asctime_r and _strtok_r functions.
