How quickly folks forget mod.sources.  The mod.sources archive contains
a program I wrote called "scpp" (for "Selective C PreProcessor") -- it
does exactly what you want.

Unlike "unifdef" or the Rand unifdef'er, Scpp is a complete reimplementation
of the functionality of Cpp -- it properly handles nasty problems like:

	#if defined(VAX) || BUFSIZ > 512
	....
	#endif
