The f77 compiler is no longer on by default and now the f2 library for the f77 does not build any 
more, can you provide the preprocessed source for rsne.c?

(From update of attachment 5490)
I should have mentioned that this fails on an x86-64 system with GCC 3.2.3 when
compiled with:

g++ -O3 -fpreprocessed -c z.ii

Demian Nave, you should have filed a different bug report, but this is fixed at least on the 
mainline and the 3.4 branch.

Anythony, if see this again, can you file a new bug.
