This looks very annoying.  Too bright.  Please try using the same
conventions as in C files.  In particular, comments should be brown, and
that applies to dnl too.

Also a common rule is to highlight only recognized constructs.  There is
no need to make everything yellow.

I think it's a good idea, but I'm not sure about brightgreen for the 
numbers.

Fine with me.

Maybe be hard if you decide to support more than on C dialect (K&R, ANSI,
C99).  Not all of them allow spaces before "#".

Maybe we need different colors for them.

Go ahead.
