Follow up.
To enable cross from Windows towards Darwin, some changes in FPC were
needed.
They have been added into NewPascal, and can be found here:

Not meant to be 100% correct, but working.
Summary:
New rtl-makefile for Darwin.
Some small changes in script.pas were needed to generate valid Windows
batch-code for Darwin.
Changes in t_bsd.pas were more than trivial.
The Windows Darwin linker does not allow pipes. So, it needs a res that
has to be serialized on the command line. But Windows limits the length
of the command line to 8196 characters. Which is not enough when linking
a lot of files in different directories. So the filelist option has to
be used on Windows. Files are added into this filelist, the rest remains
in res.
This also means that the default fpc.cfg does not work anymore, due to
the default -ap switch for Darwin. This does not work on Windows.
A very minor patch was added into the crosstools to allow the successful
find of files that are needed by the linker.

Thanks again for your help.
