Ah, thanks for your reply.

I did that and it works. However, it doesn't seem to copy any files to 
usr/local/lib/fpc/2.3.1/units/i386-win32/. I tried

When I copy some of the .o and .ppu files by hand to /usr/local/lib/fpc/2.3.1/units/i386-win32, 
crosscompiling hello.pas works.

[p17:~/fpc/testfpc] adriaan% fpc -Fu/path/to/fpc/rtl/units/i386-win32 -Twin32 hello.pas

and hello.exe actually runs at the other side of the fence.
