1998-04-11 09:33 Ulrich Drepper <drepper@cygnus.com> * Makeconfig (rtobjdir): New variable. (rpath-link): Add rtobjdir and thread directory, if available. * test-skeleton.c: Add support to remove temporary files. Always define test_dir. Improve message about expected signal. * rt/Makefile (tests): Add tst-aio. Add rules for tst-aio to be linked with librt and thread library. * rt/aio_misc.c: Correct fundamental bugs. * rt/aio_suspend.c: Correct bug in test for available request. Initialize conditional variable. * rt/lio_listio.c: Initialize conditional variable. * rt/lio_listio64.c: Likewise. * rt/tst-aio.c: New file. * sysdeps/libm-ieee754/s_signgam.c: Undo last change. * sysdeps/libm-ieee754/w_gamma.c: Likewise. Adopt for ISO C 9x. * sysdeps/libm-ieee754/w_gammaf.c: Likewise. * sysdeps/libm-ieee754/w_gammal.c: Likewise. * sysdeps/libm-ieee754/w_lgamma.c: Likewise. * sysdeps/libm-ieee754/w_lgammaf.c: Likewise. * sysdeps/libm-ieee754/w_lgammal.c: Likewise. 1998-04-11 14:49 Mark Kettenis <kettenis@landau.phys.uva.nl> * posix/regex.c [_LIBC] (__re_syntax_options): Initialize to 0. * elf/dl-load.c (open_path): Use correct name for test whether directory in load path exists. * sysdeps/libm-ieee754/s_expm1.c: Remove variable one. * sysdeps/libm-ieee754/e_pow.c: Fix typo. Patches by Tom Rini <trini@kernel.crashing.org>. * wcsmbs/wcstof_l.c: Declare ____wcstoull_l_internal. * wcsmbs/wcstod_l.c: Likewise. * wcsmbs/wcstold_l.c: Likewise.
