What are these special calling conventions exactly?  If you want to run
under Windows, you have to follow the Win32 calling conventions, at least
externally.  So I don't see the need to use special conventions, even
internally.  Can you not simply use the MSVC/MinGW ones?

The assembly routines (except a few of them, specific to the Watcom
compiler) are meant to be compiled by the GNU assembler and exported by the
DLL, so you cannot change their calling conventions.

Looks sensible.

You'd better use PE-COFF if you really have to make a choice.

fix.bat and fix.sh
