(SYSCALL_EXAMINE, MSG_EXAMINE): New inline functions. * sysdeps/mach/hurd/i386/trampoline.c (struct mach_msg_trap_args): Structure moved to intr-msg.h; include that. * time/Makefile (CFLAGS-ialloc.c): Add -Wno-unused. (CFLAGS-scheck.c): New variable. * sysdeps/mach/hurd/dl-sysdep.c (__hurd_sigthread_stack_base, __hurd_sigthread_stack_end, __hurd_sigthread_variables, __hurd_threadvar_stack_mask): New variables. * sysdeps/mach/hurd/fork.c: Set the new task's exception port to its new message port. * misc/init-misc.c: Put __init_misc in the __libc_subinit set. * configure.in (uname): Add quoting. * sysdeps/mach/hurd/fchdir.c: Don't consult errno unless lookup fails. * hurd/fchroot.c: Likewise. * posix/sys/types.h [GCC >= 2.7]: Define intN_t/u_intN_t using __attribute__ ((__mode__ (__XX__))).

Wed Feb 7 14:16:36 1996 Roland McGrath <roland@churchy.gnu.ai.mit.edu> * sysdeps/generic/Makefile (make_siglist): Get signum.h absolute file name first thing, before $(native-compile) changes directories. From Gord Matzigkeit <gord@enci.ucalgary.ca>: * sysdeps/unix/make_errlist.c: Use strerror if available. * sysdeps/unix/configure.in: New file * sysdeps/unix/bsd/sun/syscalls.list: Added sigvec. * sysdeps/unix/bsd/sun/sigvec.S: File removed. * sysdeps/stub/sendto.c: Make sockaddr arg pointer to const. * sysdeps/stub/connect.c: Likewise. * sysdeps/stub/bind.c: Likewise. * hurd/hurdlookup.c (__hurd_file_name_lookup_retry): RETRYNAME of "" is only special for FS_RETRY_NORMAL; for FS_RETRY_REAUTH, do another dir_lookup of "".
