2002-04-03 Ulrich Drepper <drepper@redhat.com> * locale/programs/charmap.c (charmap_read): If the charmap doesn't define a code_set_name provide one based on the filename. * malloc/hooks.c: Define weak_variable correctly for _LIBC. 2001-12-28 Andreas Jaeger <aj@suse.de> * time/mktime.c (__mktime_internal): Check for year < 70 [PR libc/2738]. * sysdeps/generic/w_lgamma.c: Initialized local_signgam. * sysdeps/generic/w_lgammaf.c: Likewise. * sysdeps/generic/w_lgammal.c: Likewise [PR libc/2854]. * debug/catchsegv.sh (exval): Quote [ in pattern [PR libc/2902]. Adjust for new output format of the backtrace functions. * misc/syslog.c (vsyslog): Only use cleanup handler if _LIBC_REENTRANT is defined [PR libc/2924]. * sysdeps/s390/s390-64/bits/byteswap.h: Likewise [PR libc/2757].
