[fpc-pascal] Bug in rtl/baseunix on OSX - Abort with illegal instruction

[Brad Campbell]

G'day all,

fpmkfifo aborts with an illegal instruction on OSX.

macppc:~ user$ fpc testfifo.pas
Free Pascal Compiler version 2.2.3 [2008/06/14] for powerpc

macppc:~ user$ ./testfifo
Illegal instruction
macppc:~ user$ cat testfifo.pas
Program FifoTest;

Uses BaseUnix;

Begin
Writeln(fpMkFIFO('Hello.fifo',666));
End.

This works on Linux.
I've tested it against a native PPC compile on 10.4, and a PPC & Intel cross compile from Linux.
All terminate the same way.

I'm not quite sure how to go about debugging it.

Regards,
Brad
