* Merge in changes from bash-1.13.5. Merge changes from glob/tilde.c
into tilde.c and use it. Add system function declarations where
necessary. Check for __GO32__, not _GO32_ consistently.
* Makefile.in: Update dependencies.
* rltty.c: Include <sys/file.h> to match include file setup
in readline.c for rldefs.h. Otherwise we get inconsistent
TTY_DRIVER definitions in readline.c and rltty.c.
* bind.c, complete.c: Do not include <sys/types.h>, it is already
included via sysdep.h, which causes problems if <sys/types.h> has
no multiple inclusion protection.
* readline.c (_rl_set_screen_size): Reestablish test for
TIOCGWINSZ_BROKEN.
