I suggest to experiment with lowering the stack size.  4MB should not
be needed except in extremely rare cases.  1MB or 1.5MB should be
enough.  The disadvantage of specifying a stack which is too large is
that it is allocated at startup and wastes memory when it is not used.

As "gcc -v" shows, `cpp' *is* used for preprocessing.  The problem is
most probably not with the macros themselves, but with the code that
they expand into.  Try to preprocess the source by running `cpp', and
then compile the expanded source and see if you see any difference.
I'd guess that cc1plus will do the same (i.e., gobble a lot of stack
space) with the pre-processed source as well.
