which still seems to call some non-reentrant functions on
its way to _exit(2).) That must eliminate the possibility
of catching SIGSEGV from following non-reentrant paths from
signal handlers.

errno set to 0 instead of GLOB_LIMIT when we match more than `gl_matchc'

maintain backwards compatibility.
