* sysdeps/stub/sys/sem_buf.h (union semun): New type. * sysdeps/mach/hurd/i386/init-first.c (init1) [PIC]: Call __libc_global_ctors. * sysdeps/i386/init-first.c: Rewritten. * sysdeps/unix/sysv/linux/i386/init-first.S: File removed. * sysdeps/unix/sysv/linux/i386/init-first.c: New file. * sysdeps/unix/sysv/linux/i386/fpu_control.h: Fix name in decl of ___fpu_control. * Makerules (build-shlib): New canned sequence, broken out of lib%.so rule. Link in $^ instead of just $<. (lib%.so: lib%_pic.a): Use it. (libc.so): New target; use $(build-shlib) for cmds, but also depend on soinit.so first and sofini.so last. * elf/soinit.c: New file. * elf/sofini.c: New file. * elf/Makefile (distribute): Add soinit.c and sofini.c. (extra-objs): Add soinit.so and sofini.so. * sysvipc/sys/shm.h (shmat): Fix return type to char *. * sysdeps/stub/sys/ipc_buf.h (key_t): Type removed. * misc/syslog.c (vsyslog): Rewritten using open_memstream to dynamically allocate buffers. * Makerules (install-lib-nosubdir): Make this, rather than install-no-libc.a, depend on the installed shared libraries.
