Cryptopp 5.6.3 on AIX

Has anybody successfully compiled cryptopp563 on AIX 7.1

Never heard of it before, so I have not attempted to package it.

libcrypto++ -- is this a C++ library - what do you need it for.

Further, from the changes they list looks as if they focus on gcc, not on C in general (i.e., IBM xlc) which is my preferred compiler.
