Ubuntu, which is quite a popular distro for arm systems, for some weird 
reason.  What setup issue do you think can cause an internal error in 
the bootstrap compiler?

I had no idea, so I cross compiled my own bootstrap compiler (with -gl) 
to try and debug the error, but the one I built with an up to date 
binutils simply worked.

I don't mind either way, since I tend to build my own compilers.  I just 
wanted to point out that eabi version 4 is out of date.  It was used in 
pre-releases of the abi.  I honestly don't know what the differences are 
between the versions and whether they even affect the workings of fpc. 
I thought that the linker probably wont let you link against objects 
that have a different eabi version (at least it refused to link version 
0 and 4, which is understandable).
