Yes.  What is missing is the *initialization* of the Gambit-C runtime
system (all the tables used by Gambit-C, the memory manager, the I/O
subsystem, etc).  This is done with a call to ___setup(...).  The
initialization must happen before the first call to any function your
Scheme DLL is exporting.  The best approach is probably to call
___setup(...) when the code is loaded ( i.e. the call ___setup(...)
should be in the DllMain function).  It is good style to call
___cleanup() when the DLL is unloaded.

I've copied below the code that works for me.  I'm using MinGW.
Small variations may be needed to the makefile for Cygwin and
Microsoft's compiler.

Let me know if this works with .NET .
