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
document.
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). :-)
