[plt-scheme] Using the FFI with a scheme aware dll

Dear All,

I'm currently porting the ROOS C code part (mzscheme) to
C code that can be used with the FFI. Mostly to get rid
of the version problems that are always present in the
current precompiled DLL releases.

(a precompiled 350 DLL won't work with a precompiled
350-1 DLL, etc).

Now I've ported the code to something that can be used with
the FFI, but I still need the "scheme_malloc", "scheme_make_type",
etc. functions.

How can I load these in, or feed these dynamically to my DLL?
