Sun Feb 18 15:08:10 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* sysdeps/posix/utimes.c (__utimes): There are 1000000 usecs in a sec. Sun Feb 18 13:56:00 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * elf/Makefile, time/Makefile: Make `all' the default target. Mon Feb 19 18:09:04 1996 Roland McGrath <roland@charlie-brown.gnu.ai.mit.edu> * misc/sys/ptrace.h: Moved to ... * sysdeps/generic/sys/ptrace.h: ... here. * sys/ptrace.h: File removed. Sun Feb 18 12:13:07 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * sysdeps/unix/sysv/linux/Makefile (headers): Add fpu_control.h. * sysdeps/unix/sysv/linux/i386/sysdep.S (errno): Put it into .bss so that the symbol alias works. * sysdeps/unix/sysv/linux/m68k/fpu_control.h (_FPU_SETCW): Corrected. * sysdeps/unix/sysv/linux/resourcebits.h: New file. * sysdeps/unix/sysv/linux/sys/ptrace.h: New file. * sysdeps/unix/sysv/linux/syscalls.list: Add getegid, geteuid, getppid and reboot. * sysdeps/unix/sysv/linux/sysconf.c: Special version that does not use getdtablesize. Sat Feb 17 10:30:21 1996 David Mosberger-Tang <davidm@AZStarNet.com> * stdio-common/printf_fp.c, stdlib/strtod.c, sysdeps/ieee754/dbl2mpn.c, sysdeps/ieee754/ldbl2mpn.c, sysdeps/ieee754/mpn2dbl.c, sysdeps/ieee754/mpn2ldbl.c: Cast left operands of shift instructions to `long' where necessary. Thu Feb 15 20:04:50 1996 Ulrich Drepper <drepper@gnu.ai.mit.edu> * stdlib/fpioconst.h: Introduce new constant _FPIO_CONST_OFFSET. * stdio-common/printf_fp.c, stdlib/strtod.c: Use _FPIO_CONST_OFFSET to correctly access MPN array depending on architecture.
