I added a subset of the Crypto++ 5.6.0 library to the SVN. I stripped it down to just SHA and 11 general dependency files. There shouldn't be any other crypto in there other than SHA.
I think you should be able to pare it down to at most 5 files from Crypto++, config.h, cpu.h, cpu.cpp, sha.h, and sha.cpp. Take a look at the zip file I posted on the other thread. It's just excluding some headers that aren't needed and I think I had to move 1 or 2 functions as well, ByteSwap being one if I remember.
