* sysdeps/mach/hurd/i386/Makefile (CFLAGS-init-first.c): Add
-momit-leaf-frame-pointer.
* inet/test-ifaddrs.c (addr_string): Surround AF_PACKET case with
#ifdef AF_PACKET.
* sysdeps/mach/hurd/getcwd.c
(_hurd_canonicalize_directory_name_intern): Only realloc when
size is <= 0.
* sysdeps/mach/hurd/mmap.c (__mmap): Fail when addr or offset
isn't page aligned.
* sysdeps/mach/hurd/spawni.c (EXPAND_DTABLE): Set dtablesize to
new size.
* sysdeps/mach/hurd/Versions (GLIBC_PRIVATE): Add __libc_read,
__libc_write and __libc_lseek64.
