I have just downloaded the test suite to try and resolve my problem with gpc that I posted earlier. The output from the test suite follows: $ make 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="gpc" PFLAGS=" --autobuild -g -O3 -W -Wall -Wno-unused " PFLAGS_NO_PATHS="-g -O3 -W -Wall -Wno-unused " SRCDIR="."

My problem seems to be due to the gpc/gcc distribution! Best regards, Chris.
