(Side note: that's why the STUPID_CPP option exists in NetHack).

Actually, the "hard limit" you're running into is *only* on total symbol name 
space if you're getting "Too much defining." (which is what NetHack has 
trouble with on a 3B2). Richard was running into the hard limit on *number* 
of defines. Two slightly separate but interrelated problems.

Er, this isn't the normal number U.S. AT&T customers use for the NSSC in New 
Jersey (1-800-922-0354). 

Or is that number the one for Lisle? As an AT&T person, you may be able to 
call Lisle directly on problems, but I've found that Lisle will rarely talk 
to mere mortals unless they already have an escalated ticket from New Jersey.

No, but fortunately there are public domain alternatives to AT&T's cpp. Ones
that malloc() instead of of using static arrays, for example.

Richard, if you can't beat a real cpp out of Lisle, drop me a line, and I'll
arrange to send you a decent PD cpp.
