Oh, and since I needed macro arguments to be expanded, but the macro
itself not to be, I found a simple work-around that you might want to

I rewrote this:

#define FOO(X) X

to be:

#define FOO2(X) X
#define FOO FOO2

Now I can pass -NFOO -DN=1 to Wave, and FOO(N) will be partially
expanded to FOO(1). :-)
