Update.
1998-09-22 19:58 -0400 Zack Weinberg <zack@rabi.phys.columbia.edu> * posix/execvp.c: Don't give up searching the PATH if execve returns ENOTDIR. 1998-09-22 12:53 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/init-first.c (init): Don't call setfpucw only if _dl_fpu_control_set is set. * sysdeps/generic/dl-sysdep.c: Don't set _dl_fpu_control_set. * elf/rtld.c: Don't define _dl_fpu_control_set. * elf/Versions: Remove _dl_fpu_control_set. 1998-09-22 11:51 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/linux/alpha/bits/sigaction.h (SA_ONSTACK): Define. * sysdeps/unix/sysv/linux/sparc/bits/sigaction.h: Likewise. * sysdeps/unix/sysv/linux/mips/bits/sigaction.h: Likewise. Correct values of other SA_* macros according to kernel headers. 1998-09-22 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * elf/dl-load.c (_dl_init_paths): Avoid warning about unused variable l. * elf/dl-error.c (_dl_catch_error): Avoid warning about clobbering old. 1998-09-21 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * elf/ldsodefs.h: Fix typo in comment. 1998-09-21 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * libio/genops.c (_IO_default_pbackfail): Add cast to unsigned char when comparing buffer contents with putback character. 1998-09-21 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * elf/Makefile (dl-routines, elide-routines.os, rtld-routines): Undo last change. * elf/Versions: Undo last change. Export _dl_fpu_control and _dl_fpu_control_set. * elf/rtld.c (_dl_fpu_control, _dl_fpu_control_set): New variables. Include <fpu_control.h>. * sysdeps/generic/dl-sysdep.c: Store AT_FPUCW value in _dl_fpu_control instead of __fpu_control, set _dl_fpu_control_set to indicate that is was seen. * sysdeps/unix/sysv/linux/init-first.c: Omit call to __setfpucw only if _dl_fpu_control was set and is equal to desired value. * math/Makefile (aux): Undo last change. * math/Versions: Export __fpu_control with version GLIBC_2.0.
