Win32 stub

[muta...@gmail.com]

I've tested this code as a standalone executable
built with tasm+tlink, and it all looks fine, but does
anyone know if there is anything technically wrong
with it, as I'm not familiar with the requirements of
a stub.

Thanks. Paul.

Borlands tlink32 uses "bin\winstub.exe" as the default stub. A quick peek
into that file (using debug.exe)doesn't show anything special. A boring
old minimal DOS executable is more like it. :-)
