	* coffread.c (decode_type): catch negative tagndx fields generated
	by SCO 3.2v4 cc.
	* exec.c: comment out string following #endif.
	* configure.in (i[34]86-*-sco3.2v4*): use host i386sco4.
	* xm-i386sco.h: include <sys/types.h> and <sys/dir.h>, required by
	<sys/user.h>.
	* config/i386sco4.mh: new file; like i386sco.mh, but don't require
	gcc, and define const to empty to avoid SCO 3.2v4 cc bug.
