Hi Jeff,
Thanks for answering my post again Jeff. I looked
through the xlc compiler manual, but I could not find
a compiler option that will disable the behavior of
allowing only one macro definition. I do not know how
to program in C (I use fortran,) so it really is
possible that I overlooked something. It seems like
the options that you can give to the preprocessor are
quite limited. Most of the options you can pass to
xlc are for compiling options. So I am sort of at a
loss. Well maybe I'll look over than manual again and
see if I missed anything.
