	K&R, I'd say.

	Very much so. It took me half a day (being completely new to GRASS)
	to make a port to Apollo GPR (well, I didn't test it a lot,
	but d.rast and d.vect worked just fine...)

> [3] Has anyone tried compiling GRASS using a C++ Compiler.

	Yes and no. I use GRASS libraries from C++, but there doesn't
	seem to be much point in compiling pure C code with a C++ compiler
	(new reserved words and such like).
	You need function prototypes for using GRASS functions from C++,
	these can be generated/extracted fairly efficiently using the
	GNU protoize tool together with good old vi.
	I've done this for most of the libraries, let me know if you want them.
