Turns out the X11 header file /usr/include/X11/Xlibint.h contains the
following macro definition:
#define GetEmptyReq(name, req) \
WORD64ALIGN\
if ((dpy->bufptr + SIZEOF(xReq)) > dpy->bufmax)\
_XFlush(dpy);\
req = (xReq *) (dpy->last_req = dpy->bufptr);\
req->reqType = X_/**/name;\
req->length = 1;\
dpy->bufptr += SIZEOF(xReq);\
dpy->request++
This causes the variable GetInputFocus to be rendered by the preprocessor
as "X_ GetInputFocus" instead of "X_GetInputFocus", and boom.
The kludge workaround is to add #define ANSICPP above the #include for
X11/Xlibint.h.
Not sure what the real fix is - there may be a Solaris patch for it, not
sure.
Regards,
Graham
