Matt has answered the main question, but as an aside: -D"_CRT_SECURE_NO_DEPRECATE" suppresses warning messages from Microsoft's Visual C compiler for using various standard C library functions, rather than using the optional "secure" ones (a misnomer, as they
are at best somewhat easier to use safely) added with C99 (in Appendix K of the C standard, I think; I'm traveling and don't have my copy handy). It has nothing to do with OpenSSL APIs, deprecated or otherwise; it just reduces noise from the Microsoft compiler.
