* Makeconfig (+gccwarn): Add -Winline. * hurd/hurdsig.c (_hurd_internal_post_signal): If SS->context is set, avoid abort_rpcs, and use reply and intr ports saved in SS->context. * sysdeps/mach/hurd/i386/trampoline.c: Don't set SS->intr_port from SS->context. Don't clear SS->context. * sysdeps/mach/hurd/i386/sigreturn.c: Don't set SS->intr_port when setting SS->context. If msg_sig_post returns, re-lock and clear SS->context. Fri May 5 10:37:09 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu> * mach/Makefile (errsystems.c): Comment out generation rule. * sysdeps/mach/_strerror.c: Consider a system unknown if its bad_sub member is null. * mach/mig-alloc.c: Add weak alias to non-__ name.
