Sat Apr 22 14:48:03 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu>
* mach/Machrules [interface-library] (LDFLAGS-$(interface-library:lib%=%.so)): New variable, set to -nostdlib. * sysdeps/mach/hurd/fork.c: Subfunction `unlockss' removed. Lock _hurd_siglock only around initial task creation in parent. Use _hurd_critical_section_unlock at end. Handle dead name rights properly, and deal with a send right dying while we try to copy it. For the time being, use assert_perror for kernel and proc RPC failures. Fri Apr 21 01:10:15 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu> * extra-lib.mk: Don't include $(o-iterator); construct it by hand using $(object-suffixes-$(lib)) instead. * sysdeps/mach/hurd/Makefile (LDLIBS-c.so): New variable. * Makerules (lib%.so: lib%_pic.a): Pass $(LDFLAGS-$(notdir $*).so). (LDFLAGS-c.so): New variable. * resolv/res_init.c (res_init): Don't clobber _res.options with RES_DEFAULT. If RES_INIT is clear, OR in RES_DEFAULT. * hurd/hurd.h: Declare _hurd_startup. * hurd/hurdstartup.c: New file. * hurd/Makefile (routines): Add hurdstartup.
