MS uses COFF format for it's objects and libs, same as gnu-win32. MS'
version is probably hacked. Also a common object format does not tell
you anything about other ABI issues such as calling conventions, struct
and class object layout, name mangling, exception handling, RTL support,
helper functions etc. So while it's probably more or less easy to get
GNU ld link MS objects, the results may still not work.

Borland uses OMF for object format, so it's not compatible with MS or
gnu-win32. I have heard that they added some compatibility in their
latest Builder release, such as automatic conversion of import libs in
the linker.

Just my 2 cents, benny
