Our setup:	Sun 3/60 with cgfour	SunOS 4.0 (plus what Sun calls their "general hygiene" patch tape)	XV11R3 + MIT fixes 1 through 8 + "Purdue enhancements" + one local		"ANSIfication" fix (previously reported to MIT,		and attached below)I installed gcc 1.34 (plus the expr.c fix) and also ran the "fixincludes"script.I built the X stuff with with the "CC" line in the "Sun.macros" file set to:             CC = gcc -fcombine-regs -fstrength-reduce -finline-functions -fpcc-struct-return -DPURDUE -Dinline=INLINE -DNOSTDHDRSwhere -fcombine-regs, -fstrength-reduce, and -finline-functionsspecify desired optimizations, -fpcc-struct-return makes thingscompatible with the dbm library, -DPURDUE buys the Purdue speedups,-Dinline=INLINE avoids a problem with a variable named "inline" in theX file "fonts/bdftosnf/fontutil.c", and -DNOSTDHDRS avoids a problemwith multiple (and conflicting) typedef'ing of "size_t" in thegcc-provided STDDEF_H and Sun's "sys/types.h".Some clients may need -fwritable-strings.  twm is said to need it.The ANSIfication fix:> From ado Mon Dec 26 10:55:28 1988> To: xbugs@expo.lcs.mit.edu> Subject: Xlibint and __STDC__ don't mix> > > 			  X Window System Bug Report> 			    xbugs@expo.lcs.mit.edu> > > > > VERSION:> 	R3> > CLIENT MACHINE and OPERATING SYSTEM:> 	Sun 3/60 running SunOS 4.0> > DISPLAY:> 	Sun CG4> > WINDOW MANAGER:> 	uwm> > AREA:> 	Xlib> > SYNOPSIS:> 	Xlibint.h and __STDC__ don't mix> > DESCRIPTION:> 	If __STDC__ is defined (and UNIXCPP is not defined),> 	code that uses the GetReqExtra macro defined in Xlibint.h> 	is uncompilable.> > REPEAT BY:> 	Script started on Mon Dec 26 10:52:58 1988> 	elsie$ cd lib/X> 	elsie$ rm Xbackgnd.o> 	rm: Xbackgnd.o: No such file or directory> 	elsie$ rm XBackgnd.o> 	elsie$ make XBackgnd.o CC=/usr/local/bin/gcc> 	rm -f XBackgnd.o> 	/usr/local/bin/gcc -c -O -I. -I../../. -I../.././X11  -DTCPCONN -DUNIXCONN XBackgnd.c> 	XBackgnd.c: In function XSetWindowBackground:> 	XBackgnd.c:16: undeclared variable `sz_' (first use here)> 	*** Error code 1> 	make: Fatal error: Command failed for target `XBackgnd.o'> 	elsie$ exit> > 	script done on Mon Dec 26 10:53:51 1988> > SAMPLE FIX:> 	*** 1.1/Xlibint.h	Mon Dec 26 10:39:37 1988> 	--- 1.2/Xlibint.h	Mon Dec 26 10:39:37 1988> 	***************> 	*** 122,133 ****> 	  #if defined(__STDC__) && !defined(UNIXCPP)> 	  #define GetReqExtra(name, n, req) \> 		  WORD64ALIGN\> 	! 	if ((dpy->bufptr + SIZEOF(*req) + n) > dpy->bufmax)\> 			_XFlush(dpy);\> 		req = (x##name##Req *)(dpy->last_req = dpy->bufptr);\> 		req->reqType = X_##name;\> 	! 	req->length = (SIZEOF(*req) + n)>>2;\> 	! 	dpy->bufptr += SIZEOF(*req) + n;\> 		dpy->request++> 	  #else> 	  #define GetReqExtra(name, n, req) \> 	--- 122,133 ----> 	  #if defined(__STDC__) && !defined(UNIXCPP)> 	  #define GetReqExtra(name, n, req) \> 		  WORD64ALIGN\> 	! 	if ((dpy->bufptr + SIZEOF(x##name##Req) + n) > dpy->bufmax)\> 			_XFlush(dpy);\> 		req = (x##name##Req *)(dpy->last_req = dpy->bufptr);\> 		req->reqType = X_##name;\> 	! 	req->length = (SIZEOF(x##name##Req) + n)>>2;\> 	! 	dpy->bufptr += SIZEOF(x##name##Req) + n;\> 		dpy->request++> 	  #else> 	  #define GetReqExtra(name, n, req) \> -- > 	Arthur David Olson    ado@ncifcrf.gov    ADO is a trademark of Ampex.
