Hi Camm,
Including "-g" in the GCL compiler's command line wasn't as straight
as I thought (somehow the use of LINK seems to forget that setting)
I believe I've managed to convince GCL. The numbers are in:
* pristine OpenAxiom (trunk)
make 1624.70s user 102.77s system 99% cpu 28:57.07 total
* modified OpenAxiom
make 1672.23s user 107.45s system 100% cpu 29:35.42 total
this is with GCL-2.6.8pre on a dual-core with 4GB RAM, and 4GB cache
size each at 2.40Gz, running opensuse-10.3.
