I'd suggest using "none" as the LLDS base grade. "reg" certainly worked
with OS X 10.3 and 10.4 on PPC, but I don't think we ever tested it with
10.5 on PPC. (That was the point that the Intel Macs came out.)
My suggestion would be to avoid the low-level C backend on this platform
unless it is absolutely required (e.g. for debugging or deep profiling).
A reasonably minimal set of grades that would meet the above
requirements might be:

There is no "probably" about it, hlc.gc *is* a lot faster then reg.gc.
