OCaml 3.11.0 isn't really set up to do cross-compilation. For the
Fedora Windows cross-compiler (which targets 32 bit Windows only at
present) we build a 32 bit Linux native compiler first, even if the
build arch is 64 bit. Ugly details here:
http://hg.et.redhat.com/cgi-bin/hg-misc.cgi/fedora-mingw--devel/file/3a93f6f65967/ocaml/mingw32-ocaml.spec#l100
The changes required to make OCaml a true cross-compiler would be
quite deep, and if I had 3 or 4 clear weeks I would love to come up
with a good set of patches to do this and submit them back to INRIA.
Unfortunately I haven't got 3 or 4 free days never mind weeks at the
moment ...
Rich.
