The compiler does build on powerpc-apple-darwin8 with gcc-4.0.3 (I  
bootstrapped an FSF-gcc-4.0.3 C compiler first). Next I tried the  
testsuite.

rm -f *.dat *.o *.s *.i *.gpi *.gpd *.gpc core a.out stderr.out *.exe  
testmake.tmp dummy.c dummy.pas dummy.out diff_cr*.tmp fixcr fixcr.exe
rm -f todo/a.out todo/*.exe todo/*.o todo/*.s todo/*.i todo/*.gpi  
todo/*.gpd todo/core
GP= PC="gpc403d1" PFLAGS=" --autobuild   -g -O3 -W -Wall -Wno-unused   
" PFLAGS_NO_PATHS="-g -O3 -W -Wall -Wno-unused  " SRCDIR="."  
TEST_MAKE_FLAG=test-make-flag "./test_run"  "*.pas" | tee test_log |  
"./test_sum" -d

Looks like the compiler hangs in an endless loop. I took a sample  
with the Mac OS X activity monitor.

	Analysis of sampling pid 2816 every 10.000000 milliseconds
	Call graph:
	    289 Thread_100f
	      289 start

	                                289 dbxout_symbol
	                                  289 dbxout_symbol

	Total number in stack (recursive counted multiple, when >=5):

	Sort by top of stack, same collapsed (when >= 5):
	        dbxout_symbol        289
	Sample analysis of process 2816 written to file /dev/stdout
	Sampling process 2816 each 10 msecs 300 times

The same happened with another test program (but I didn't come very  
far yet). Adding -O2, -O1 or -O0 doesn't help. Same for -mdynamic-no- 
pic and --no-pic.


Interestingly, asmnames.pas now passes.

rm -f *.dat *.o *.s *.i *.gpi *.gpd *.gpc core a.out stderr.out *.exe  
testmake.tmp dummy.c dummy.pas dummy.out diff_cr*.tmp fixcr fixcr.exe
rm -f todo/a.out todo/*.exe todo/*.o todo/*.s todo/*.i todo/*.gpi
