Out of curiosity I've built a 2.0.2 cross-compiler on an i386 and transferred it
to a SPARC system. This builds hello.pp OK, but applying it to the same 2.0.4
source (or, for that matter, to 2.0.2 source) gives me a slew of exceptions
similar to:

/usr/local/fpc-2.0.2x/bin/ppcsparc -Fi../inc -Fi../sparc -Fi../unix -Fisparc
-FE. -FU../../rtl/units/sparc-linux -dsparc -Us -Sg system.pp
Free Pascal Compiler version 2.0.2 [2006/08/05] for sparc

So the current situation appears to be (working from memory) that 2.0.0 will
compile itself, bombs compiling 2.0.2, and gives a sensible error trying to
compile 2.0.4 (Jonas?); 2.0.2 bombs trying to compile either 2.0.2 or 2.0.4
sources.

I guess that's the last time I look at 2.0.2- it's obviously got problems.
