I'll agree here, there are two slightly sepreate but interrelated problems.  
The fix I have, however, fixes both problems.

Having to use the "STUPID_CPP" option when compiling nethack goes away after 
you apply the fix that I received.

Sorry, being in Canada, that's the number I call to get through to the NSSC.
Your Mileage may vary...

Agreed, but given the knowledge of what the problem is, you should be able to 
get the patch directly from the NSSC.

That's problem one, the second cause/symptom fixed by the patch is as follows:

Symptom: too much defining

Cause: the amount of text for defines and includes exceeds the buffer
        if ( savch > sbf + SBSIZE - BUFSIZ )

Actually, I'd love to see it.
