This error has pointed out something to me that may need fixing, but I
am still surprised that gcc will not let you compile it (while it works
here).

Initially it looked like CS_VOID was not defined for some reason (and
you can test to see if this is the case by adding

#ifnef CS_VOID
#define CS_VOID void
#endif

near the top of CTlib.xs)

However, after some closer analysis, I see that the first error happens
when constant() tries to return CS_BLKDESC, which is normally
typedef'ed to 'struct _cs_blkdesc. Aha! Normally, this would mean the
CS_BLKDESC is *not* #define'd, so the code

		if (strEQ(name, "CS_BLKDESC"))
#ifdef CS_BLKDESC
		    return CS_BLKDESC;
#else
		goto not_there;
#endif

should compile the 'goto not_there' branch. (I verified this here by
trying this little script:

kiruna (8:20am):32 > perl -e 'use Sybase::CTlib; print &CS_BLKDESC, "\n";' 

Your vendor has not defined Sybase::CTlib macro CS_BLKDESC, used at -e line 1 (main).
kiruna (8:21am):33 > 

We are getting closer :-)

So now we take a look at the Sybase include files again, and find that
CS_BLKDESC *can* end up #define'd (as CS_VOID) *if* 'lint is #define'd
(see cspublic.h, around line 750). So it looks like your copy of gcc
thinks that it is lint, or that something else #defines 'lint' (or that
your copy of cspublic.h is somhow munged...)

In CONFIG, try adding -Ulint to the EXTRA_DEFS line, and see what happens...

Hope this helps, and isn't totally confusing the issue :-)
