I just tried to compile all the Algol 68 testsuite files
with a recent gcc trunk compiler:
I found:
testsuite $ ~/gcc/results.a68/bin/ga68 -c -w -fstropping=upper
./algol68/compile/upper-1.a68
testsuite $ ~/gcc/results.a68/bin/ga68 -c -w -fstropping=upper -O1
./algol68/compile/upper-1.a68
testsuite $ ~/gcc/results.a68/bin/ga68 -c -w -fstropping=upper -g -O1
./algol68/compile/upper-1.a68
