Compiling llcurl.cpp looks for openssl/crypto.h, because SAFE_SSL is defined for all platforms, but does not find it. This comment is in llblowfishcipher.cpp, "We do not have OpenSSL headers or libraries on Windows, so this class only works on Linux." So apparently SAFE_SSL should not be defined for MS Windows. Commenting out the define allows it to compile. Is this the right solution or should openssl be in the libraries distribution, or do we need to find it somewhere?
