Unfortunately this is not really the case. Due to the nature of the win32 build,
it will always require some to adept and fix the build script. As you might have
noticed, the win32 build comes with a completely different makefile than the
linux build. The linux makefile is maintained by the people commiting to trunk,
but the win32 file is not maintained by anyone, except if I do it. I.e. if a
file is added, the win32 build wont work until this file is also added to the
win32 makefile.

Also, the win32 build always takes a lot of overhead to fix (downloading,
compiling the fixed verison packages...). I.e. if I fix 3 little details once
maybe I need 3 hours, but if I fix at first the first issue, then a week later
a second issue and later a third issue, I will end up spending 2 hours oneach
problem...

The clean solution would be to share the makefile / build environment on linux
and windows(Cross compiled), but this would require rewriting mostly the build
system, which is a _huge_ undertaking (I tried something like that last year
but aborted aftertwo weeks of nearly no progress)...
