It would be great if Debian could push changes for cross-compilation
back upstream. Perhaps this is something we will be able to discuss
at the OCaml Users Conference in April?

In Fedora we maintain over 100 mingw32-* packages (not OCaml
specifically, but many C and C++ libraries), and there are often quite
a lot of changes from upstream and from the native package. I'm
afraid that "minimal modification" is going to be very hard to
achieve. Of course it's always something to aim towards, but maybe
not this decade :-(

Oooo, I don't like this at all. This is not necessary for any Fedora
cross-compiled packages, so I'm not clear why it should be needed for
Debian ones.

Non-disfunctional libjpeg upstream
by Richard W.M. Jones
http://sourceforge.net/projects/libjpeg-turbo/
libjpeg-turbo is a version of libjpeg which uses MMX, SSE, and SSE2
SIMD instructions to accelerate baseline JPEG compression/
decompression by about 2-4x on x86 and x86-64 platforms. It is based
on libjpeg/SIMD but has numerous enhancements.
I talked privately to Adam Tkac who is involved with this project, and
he is very interested in receiving any Windows / cross-compiler
patches that we may be carrying. This looks like a good project, and
hopefully at some point we (and Fedora) can switch over to using this
instead of vanilla libjpeg. There are obvious benefits for Windows
32-bit and 64-bit users.
