Gee, you're right.  I've never thought of that.  I've never used #ifdefs
for that reason.  Of course, it would be a perfectly acceptable extension
to Fortran to allow ordinary IF statements in this sort of context (with
only constant conditional expressions of course).  Still, I've never
seen a compiler which would take that - score one for you! 

But then, back to my original point.  Use #ifdef with your Fortran code.
C does _not_ have a monopoly on preprocessors.
