On Windows, there are two different calling conventions
for C subroutines. The Translator expects all C routines
in a .dll to use the __stdcall convention. This is the convention
used by all WIN32 API routines. From what Todd Riggins
tells me, Exotica uses the __cdecl convention. 

By luck, the interpreter, compiled by WATCOM C, will not crash
if the .dll is __cdecl, though there might be a problem with returning
a C double, I'm not sure. I think it works because 
c_proc/c_func returns almost immediately after calling the 
.dll routine, and WATCOM-generated code manages 
to reset the incorrect stack pointer before it is used. 
So I recall that the Translator worked with WATCOM,
but not Borland or Lcc.

However, Todd says he tried rebuilding his .dll using __stdcall 
and things still didn't work. So we aren't sure what to do about it.
