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).

	* signal/Makefile (routines): Add sigisempty, sigandset, and
	sigorset.
	* signal/signal.h: Add prototypes for sigisempty, sigandset, and

	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.

	* sysdeps/unix/sysv/linux/netinet/icmp.h: Remove since we have
	ip_icmp.h.  Reported by HJ Lu.

	* sysdeps/m68k/Makefile (CFLAGS-rtld.c): Add -Wno-unused.

	* sysdeps/m68k/dl-machine.h (elf_machine_rela): Rewritten as for
	i386.

	* sysdeps/unix/sysv/linux/termbits.h (OXTABS): Don't define.
	* sysdeps/unix/sysv/linux/alpha/termbits.h (OXTABS): Likewise.

	* termios/sys/ttydefaults.h (TTYDEF_OFLAG): Use either OXTABS or
	TAB3, if one of them is defined.

1997-03-26 04:53  Ulrich Drepper  <drepper@cygnus.com>

	* posix/glob.c (next_brace_sub): Decrement depth counter when '}'
	is found.
	Patch by Dennis Henriksen <opus@flamingo.osrl.dk>.
