Subject: * syswait.h: Remove old if 0 code.  Do not define WAITTYPE, it was
 always defined as int.

* s/netbsd.h (HAVE_UNION_WAIT, HAVE_WAIT_HEADER, WAIT_USE_INT):
* s/gnu.h (HAVE_WAIT_HEADER, WAIT_USE_INT, HAVE_UNION_WAIT):
* s/gnu-linux.h (HAVE_WAIT_HEADER):
* s/freebsd.h (HAVE_WAIT_HEADER):
* s/bsd-common.h (HAVE_UNION_WAIT):
* s/aix4-2.h (HAVE_WAIT_HEADER):
* m/mips.h (HAVE_UNION_WAIT):
* s/usg5-4.h (HAVE_WAIT_HEADER, WAITTYPE): Do not define, not used.
(COFF, static): Do not define, they are undefined later in the file.

* process.c (update_status): Don't use a union.
(status_convert):
(sigchld_handler): Use int instead of WAITTYPE.

* movemail.c (main): Use int instead of WAITTYPE.
