Nope.  autoconf and automake are weak on this.

I think using cpp is a mistake anyway.  My reason is that the cpp
developers tell us over and over not to use cpp for non-C/C++ uses.
And, we've seen in the past that they are willing to change cpp to
benefit C and C++ at the risk of breaking other users.  Finally I
think we don't want to even open the door to #include.  So I think we
ought to just make our own mini preprocessor, perhaps using awk.
