Under Windows, I think #f searches only exports of the current
program's ".exe", whereas #f under Unix searches all shared libraries
that are part of the program.

Maybe `ffi-lib' should automatically check the MzScheme DLL when given
#f. Meanwhile, see "mzssl.ss" in the "openssl" collection for code to
find the MzScheme DLL.
