[Bug c/20043] New: transparent_union doesn't allow restrict qualifier removal

["roland at redhat dot com" <gcc-bugzilla at gcc dot gnu dot org>]

GCC 4 now produces a "conflicting types" error for code that gcc 3.4 accepts
without complaint.  This usage pattern occurs when using glibc's <sys/socket.h>
with _GNU_SOURCE defined, followed by a POSIX-compliant redeclaration of
function like `accept'.  This is what transparent_union was invented to support.
