RSA & IDEA

[Juergen A. Erhard]

Hash: SHA1

In theory, the following patch would make installation of RSA and IDEA
simpler.  For RSA, it works to just copy rsa.c to the cipher directory
before ./configure-ing.

It could be made better two different ways:

   + make all add-on modules have some lines specially marked (like
     rsa.c has a tab in front of the gcc line) OR

   + simply have the same compile line for all modules.

The best would probably be some `Makefile:' line(s) in the .c file,
which configure.in could stuff verbatim into an autoconf
substitution... which would get inserted into the Makefile.

What do y'all think?

Bye, J
