Guile with win32 cross compiling

[Volker Grabsch]

Hello Mike,

I just tried again to cross compile a win32 version of guile, using
the latest 2.0.0 release. My last attempt in April 2010 failed.

Much has been improved since then, but there are still fatal
errors, so I still can't support guile-2 in mingw-cross-env. [1]


1)

The first issue is the "#include <uniconv.h>" in gen-scmconfig,
which has already been discussed in the past and for which I
already provided a clean, working solution. I forward-ported
my patch to guile-2.0.0 and it seems to work. This patch is
attached to this email, please consider applying it.

Also attached is a build log created by mingw-cross-env showing
how far the cross build gets with this patch.


2)

The other open issue is also a known one: the missing mmap()
function under Windows. After some research, I found a promising
mmap()/munmap() implementation for Windows in a free software
project:

http://code.google.com/p/flvmeta/source/browse/trunk/src/mmap.c?r=74

Maybe this is worth integrating into guile?



Greets,
Volker
