Summary: use an array, not a string constant.  PD preprocessor?

[]

The 'trick' was (?): instead of sizeof("string constant") (fails in Megamax)
use sizeof(array name).  So in the example at hand:
	char prompt[] = "gnuplot>"
	#define PROMPT prompt
	...
	...sizeof(PROMPT)...	/* original code unchanged */

A problem with Megamax is that there is no way to _just_ use the preprocessor.
Sometimes you might want to check out what's happening in some tricky macro
expansion, sometimes you might want to use the preprocessor for a purpose
unrelated to C (other languages, even word processing!).  (To defend Megamax:
they did it this way to keep the compiler small and fast.)  Another problem
is that the preprocessor is not documented in the Megamax docs _nor_ in the
C 'bible' (K&R) (not fully, anyway).

So: is there a PD C preprocessor (text->text) out there, preferably in C
source code form?
