I modified gcc 1.33 and X11 with your patches and I still can't compile the
core distribution. I am running a MicroVAX II, Ultrix 2.2, X11R3
with patches 1-7 installed and the PURDUE 2.0 and 2.1 enhancements
The examples in PROBLEMS 1 and 2 below actually occurred in many different
locations.

(this worked with gcc 1.31 and -traditional)

******* PROBLEM 1 *******
I can't compile the libraries without -traditional, for example, the
following macro in lib/X/XBackgnd.c, gets expanded as follows:

    GetReqExtra (ChangeWindowAttributes, 4, req);

------ gcc -E -traditional gives:
    	if ((dpy->bufptr + 12 +  4) > dpy->bufmax)	_XFlush(dpy);	 req = (xChangeWindowAttributesReq *)(dpy->last_req = dpy->bufptr);	 req->reqType =        2        ;	 req->length = (12 +  4)>>2;	dpy->bufptr += 12 +  4;	dpy->request++;

------ gcc -E gives (lots of errors about sz_):
     	if ((dpy->bufptr + sz_* req  +  4) > dpy->bufmax)	_XFlush(dpy);	 req = (xChangeWindowAttributesReq *)(dpy->last_req = dpy->bufptr);	 req->reqType =        2        ;	 req->length = (sz_* req  +  4)>>2;	dpy->bufptr += sz_* req  +  4;	dpy->request++ ;


******** PROBLEM 2 ********
There are problems in handling the asm statements from the PURDUE changes.
For example, in server/ddx/mfb/mfbgetsp.c line 118

	    getandputbits0(psrc, srcBit, w, pdst);

------- gcc -E gives:
	    { register unsigned int _tmpbits; asm ("extzv %1,%2,%3,%0" : "g" ( _tmpbits) : "g" (   srcBit), "g" (   w), "m" (*(char *)(psrc)));  asm ("insv %3,%1,%2,%0" : "m" (*(char *)(    pdst)) : "g" (   0), "g" (    w), "g" (_tmpbits)); };

which results in the errors:

mfbgetsp.c: In function mfbGetSpans:
mfbgetsp.c: output operand constraint lacks `='
mfbgetsp.c: output operand constraint lacks `='
