You really should use a mingw-compiled openssl instead.  Trying to
dynamically load cygwin1.dll is not straightforward.  (Even though you
are loading cygcrypto.dll this will cause cygwin1.dll to load so you
have to follow the same procedure.)  You'll need to ensure that there is
scratch space at the bottom of the stack, and you'll have to initialize
the DLL with cygwin_dll_init() once loaded.  See the "cygload" source
and the FAQ.
