Well, I understand by cross-platform anything that is implemented on
multiple platforms, so once ar archives can be generated for multiple ones,
it makes sense for me. :-)

And of course that is COFF as well. MSVC only supports COFF.

There isn't only one kind of COFF, AFAIK MS has an own COFF style and MSVC
supports only that. Sure, Intel must have used MSVC ones. However, my
*suggestion* about LacaK confirming that was just because he can generate
an object or a shared library from a MS COFF file, solving his problem!
