Sat Sep 21 23:42:39 1996 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu> * sysdeps/mach/getsysstats.c: Include <sys/sysinfo.h>. (__get_nproc_conf): New function. Sat Sep 21 14:59:22 1996 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu> * sysdeps/mach/getsysstats.c: New file. * shlib-versions (*-*-gnu*): Increment libc to 0.2 for upcoming binary distribution. * sysdeps/mach/hurd/Makefile (rtld-installed-name): Provide definition to override dangerous one in Makeconfig. * hurd/Makefile (install-headers-nosubdir): Install <rpc/netdb.h>. ($(includedir)/rpc/netdb.h): New rule. [ This is XXX until sunrpc can be built; <rpc/netdb.h> is essential. ] Fri Sep 20 16:06:06 1996 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu> * sysdeps/mach/hurd/i386/init-first.c (_dl_start): Add definition, to guarantee link errors if this is included in ld.so. Thu Sep 19 23:36:19 1996 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu> * hurd/hurdinit.c (__libc_argv): Provide common decl. (_hurd_setproc): Don't declare __libc_argv here. Tue Sep 17 10:51:58 1996 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu> * malloc/memalign.c (memalign): Only acquire __libc_malloc_lock for actual modifications to global state. Fri Sep 13 01:21:36 1996 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu> * sysdeps/mach/Makefile (includes): Add -I$(common-objpfx)mach/. * sysdeps/mach/hurd/Makefile (includes): Add -I$(common-objpfx)hurd/. Reported by Marcus Daniels. * sysdeps/generic/schedbits.h (struct sched_param): Renamed from struct sched_params. * sysdeps/stub/sched_setp.c (__sched_setparam): struct sched_params -> struct sched_param. * sysdeps/stub/sched_getp.c (__sched_getparam): Likewise. * sysdeps/stub/sched_sets.c (__sched_setscheduler): Likewise. Thu Sep 12 23:58:25 1996 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu> * sysdeps/mach/libc-lock.h (__libc_cleanup_region_start): Fix syntax error. * stdio-common/Makefile: Put lockfile in routines unconditionally. * stdio-common/vfprintf.c (__flockfile, __funlockfile): Declare this always, not just if _LIBC_REENTRANT. (__funlockfile): Don't use weak_extern for this one; __libc_cleanup_region_end might be defined and the use of __funlockfile can't be protected the way the use of __flockfile can be.
