1997-02-24 23:05 Wolfram Gloger <wmglo@dent.med.uni-muenchen.de> * malloc/malloc.c (malloc_get_state): New function. Saves global malloc state to an opaque data structure which is dynamically allocated in the heap. * malloc/malloc.c (malloc_set_state): New function. Restore previously obtained state. * malloc/malloc.h: Add declaration of malloc_get_state() and malloc_set_state(). 1997-02-24 23:27 Ulrich Drepper <drepper@cygnus.com> * sysdeps/libm-ieee754/s_cbrtl.c: Shift B1_EXP value to right position. 1997-02-24 17:38 Ulrich Drepper <drepper@cygnus.com> * misc/error.c: Make error and error_at_line weak aliases of __error and __error_at_line respectively.

Agnew <jtagnew@amherst.edu> * glibcbug.in: Don't mention destination on MAIL_AGENT command line to avoid duplicate mail. 1997-02-24 03:51 Ulrich Drepper <drepper@cygnus.com> * Makefile (distribute): Add isomac.c. (tests): Run isomac test. * features.h (__USE_ISOC9X): New macro. * catgets/catgets.c: Don't use global variable `optind'.

Same for NaN where NAN or nan is printed. Specified in ISO C 9X. * misc/sys/cdefs.h (__restrict): Define to empty string for now. * stdio/stdio.h: Add __restrict to prototypes where necessary. * libio/stdio.h: Likewise. * stdlib/stdlib.h: Likewise. * string/string.h: Likewise. * time/time.h: Likewise. * wcsmbs/wchar.h: Likewise. * stdlib/strtod.c: Change to recognize INF, INFINITY, NAN, and NAN(...). * sysdeps/ieee754/huge_val.h: Define HUGE_VALF and HUGE_VALL instead of HUGE_VALf and HUGE_VALL. * stdlib/strtof.c (FLOAT_HUGE_VAL): Use standard name HUGE_VALF instead of HUGE_VALf. * wcsmbs/wcstof.c: Likewise. * stdlib/strtold.c (FLOAT_HUGE_VAL): Use standard name HUGE_VALL instead of HUGE_VALl. * wcsmbs/wcstold.c: Likewise. * sysdeps/posix/gai_strerror.c: Use size_t for counter variable to avoid warning. * wcsmbs/Makefile (routines): Add wcscasecmp and wcsncase. * wcsmbs/wchar.h: Add prototypes for wcscasecmp and wcsncase. * wcsmbs/wcscasecmp.c: New file. * wcsmbs/wcsncase.c: New file. * stdlib/strtol.c: Define wide character quad word functions as wcstoll and wcstoull and normal versions as strtoll and strtoull. * wcsmbs/wchar.h: Add prototypes for wcstoll and wcstoull. * wcsmbs/wcstoq: Renamed to wcstoll.c. * wcsmbs/wcstouq: Renamed to wcstoull.c. * wcsmbs/wcstoll.c: Renamed from wcstoq.c.
