Subject: Build incorrect crypt/decrypt in Win32. x86. MSVC 2003. MinGW.

Hello openssl Hackers.
I am beginner in openssl. Learn for wrote simple crypto_test.cpp program. Test
it under CentOS, FreeBSD and Win32.
Linux,BSD work fine, but windows builds uncorrect.
Build in MS VC .Net 2003 and MingGW, both not work in crypt/decrypt cycles
correctly.
Send code in attach, and openssl makefile and simple description in README.TXT
I can't understand. is it a bug or my build problems.
Please, show right way.
Thank you.
Nick.
