The idea.c commonly found does only work up to gpg 1.0.7.

If you've got only a few files, easiest thing is probably to just
compile 1.0.7 to decrypt these files. If you can't make the sender send
further files in non-idea ciphers, you need an updated idea.c (and iirc,
since the loadable module concept was dropped, you have to build gpg
yourself with the new idea.c in the source dir. No, I don't know where
to get that new idea.c file).

Then use signatures and encryption.
