* gmon: New directory of profiling code, incorporated from
4.4BSD-Lite and modified.
* sysdeps/i386/machine-gmon.h: New file.
* sysdeps/stub/machine-gmon.h: New file.
* sysdeps/mach/hurd/profil.c: New file.
* sysdeps/stub/profil.c: New file.
* sysdeps/unix/bsd/profil.S: New file.
* Makefile (subdirs): Add gmon.
* csu/gmon-start.c: New file.
* csu/Makefile (extra-objs): Add gmon-start.o,
g$(start-installed-name).
(install-lib, omit-deps): Add g$(start-installed-name).
($(objpfx)g$(start-installed-name)): New target.
* sysdeps/generic/sysd-stdio.c (__stdio_reopen): Return failure
when __stdio_open fails with a code other than ENFILE or EMFILE.
* csu/initfini.c (SECTION): New macro, different definitions for
#ifdef HAVE_ELF and not.
(_init, _fini): Use that macro.
* config.make.in (have-initfini): New variable, set by configure.
* conf/portability.h (NEED_INETADDR, NEED_INETATON): New macros.
[$(have-initfini)=yes]: Test this rather than $(elf) for crtstuff.
[start-installed-name-rule]: If this is defined, elide rule for
$(objpfx)$(start-installed-name).
* sysdeps/unix/sysv/sco3.2.4/Makefile [$(subdir)=csu]
(start-installed-rule, start-installed-name-rule): New variables;
specify crt1.o, created by our own rule.
($(objpfx)crt1.o): New rule.
* configure.in: Require autoconf 2.4.2 or later. Change all
AC_CACHE_VAL uses to use new AC_CACHE_CHECK macro instead;
prettify some messages.
[$elf!=yes] (libc_cv_have_initfini): New test for `.init' and `.fini'
sections.
* munch-tmpl.c [HAVE_INITFINI]: Call _init and atexit (_fini) in
this case rather than #ifdef HAVE_ELF.
* config.h.in (HAVE_INITFINI): New macro.
* csu/Makefile (crtstuff): New variable consolidates crti, crtn;
add crti_s, crtn_s.
(install-lib, extra-objs, generated-, omit-deps): Use that.
(initfini): New canned sequence, broken out of crt[in].s rule.
(crt[in].s rule): Use it.
(crt[in]_s.s): New rule.
* csu/initfini.c (GLOBAL): New macro; define it to empty if undefined.
(_init, _fini): Use GLOBAL as storage class.
Add self reference to avoid GCC optimizing out the functions.
* Makefile (headers): Remove $(stddef.h).
* Makeconfig (stddef.h): Variable removed; now require gcc version
>= 2.2.
* stddef.h: File removed.
Mon Feb 20 19:42:31 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu>
* sysdeps/unix/bsd/ultrix4/mips/start.S: Remove `__environ'
definition.
* sysdeps/unix/bsd/osf1/alpha/start.S: Likewise.
* stdlib/strtod.c: Allow the string to start with a decimal point
without a leading zero.
