I've successfully compiled and installed openssl 0.9.9 with Microsoft C/C++ compiler, but in MinGW, in the config step, this error generates:
RC4_CHUNK is undefined e_os2.h => include/openssl/e_os2.h "making $target in $dir..." 'TOP' is not recognized as an internal or external command, operable program or batch file. make: *** [links] Error 1
