Update.
1997-03-27 02:28 Ulrich Drepper <drepper@cygnus.com>
* gmon/gmon.c (monstartup): Mark all messages.
(write_call_graph): Rewrite to use larger I/O vector for writev
call to reduce syscall overhead.
(write_bb_counts): Simplify writev handling.
* inet/rexec.c: Make string parameters `const'.
* resolv/netdb.h: Add prototypes for rcmd, rexec, ruserok, and
rresvport.
* math/Makefile: Don't define CFLAGS-* macros to prevent inlining
in libm-test.
* math/libm-test.c (this_does_nothing): Remove functions. It's
notuseful on any platform but ix86.
(inverse_func_pair_test): Don't use this_does_nothing. Use
memory reference.
(identities1_test): Likewise.
(identities2_test): Likewise.
(identities3_test): Likewise.
(basic_test): Likewise.
Patch by Andreas Schwab.
(BUILD_COMPLEX): New macro. Create complex number from real and
imaginary parts. This works around bugs/inefficiencies in current
gcc.
(cexp_test): Use BUILD_COMPLEX. Add more tests.
* nss/nsswitch.c: Fix typo.
* posix/glob.h: Add declaration for glob_pattern_p.
* posix/glob.c: Rename glob_pattern_p to __glob_pattern_p and
make glob_pattern_p a weak alias. This function is used in other
packages (e.g. bash).

sigorset.
* signal/signal.h: Add prototypes for sigisempty, sigandset, and
sigorset.

and __sigorset.
* sysdeps/unix/sysv/linux/sigset.h: Likewise.
* stdlib/strtod.c: Handle `n-char-sequence' in NaN parsing. It
determines the bits in the mantissa part of the NaN.
* stdlib/strtof.c: Define SET_MANTISSA for float type.
* wcsmbs/wcstof.c: Define SET_MANTISSA for float type.
* stdlib/strtold.c: Define SET_MANTISSA for long double type.
* wcsmbs/wcstold.c: Define SET_MANTISSA for long double type.
* sysdeps/libm-ieee754/s_cexp.c: Use explicit assignment to
complex number components. Some more corrects for special cases.
* sysdeps/libm-ieee754/s_cexpf.c: Likewise.
* sysdeps/libm-ieee754/s_cexpl.c: Likewise.
* sysdeps/sparc/elf/start.S: Remove as per request of Miguel de Icaza.

ip_icmp.h. Reported by HJ Lu.
1997-03-25 03:50 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* sysdeps/m68k/Makefile (CFLAGS-rtld.c): Add -Wno-unused.
* sysdeps/m68k/dl-machine.h (elf_machine_rela): Rewritten as for
i386.
(elf_machine_lookup_noexec_p, elf_machine_lookup_noplt_p,
ELF_MACHINE_RELOC_NOPLT): Define.
