Also a requirement to build many low level things with gcc - and if/when
we get more 'mounting' capability, a logical extension to that is the
ability to provide _real_ win32 mounting - and that will require
fastcall AFAIK.

AFAIK it's simply the symbol convention in the object file that is the
issue.
