As MS will want to maintain compatibility with old versions of programs
comipled with their own tools, they will probably keep the various
mechanisms in `msvcr*.dll' as they are. You think it is possible to use
whatever mechanism the MS tools use? In the end, MS-win shouldn't be
able to tell which program is MS-compiled and which is not.

Some reverse-engineering will be required.

I know... :-) I'm always welcome to do it myself.

Has anyone tried to do this before?
