I'm currently cross-compiling the MacOS RTL for PPC on a PC. I've
fixed some trivial issues that had crept in since this was last

Allowing that system.pp ends at line 570, I presume that something
after line 481 is confusing the compiler. Any suggestions would be
appreciated.
Not necessarily. It seems to be related to something "external".
You could try the following by adjusting the compiler source: before the
internalerror (in compiler/powerpc/agppcmpw.pas) add a
"writeln(tasmsymbol(p).typ)" and maybe also a "AsmFlush" so that the
assembler file up to the error will be written so you can see in which
function the problem exists.

AT_NONE
system.pp(571) Fatal: Internal error 2003090901
Fatal: Compilation aborted
./units/powerpc-macos/system.s is 28 bytes, containing only
string asis
aligning off
You could also debug the compiler (copy the command line from the
Makefile's output) when compiling the system unit and place a breakpoint
on the internalerror and then investigate the "p" variable.
I'm not very good with gdb (noting also Pierre's contribution, but it's
probably somewhat ahead of my skills at the moment). How do I get the
true name of the place I need to set the breakpoint?
