Congrats on getting OpenSSN to compile.
One suggestion though regarding DATADIR. The DATADIR value is supposed to point to the top level of the OpenSSN directory tree. So, for example, if you had
C:\Program Files\OpenSSN\data
C:\Program Files\OpenSSN\sounds
C:\Program Files\OpenSSN\ships
C:\Program Files\OpenSSN\images
Then DATADIR should be "C:\Program Files\OpenSSN". If it's working as-is right now, it's probably because the files.cpp module also checks the current working directory if it doesn't find what it's looking for in DATADIR.
I'll make a note of your other changes so the next version of OpenSSN will be easier to work with. Thanks!
PS. If you'd like to e-mail me a ZIP file with your binary and data files, I'll upload it to the project's website so everyone has easy access to it.
