Hmmm,
Is there something wrong with your system, Bruce? My 64MB
333MHz singe-PII (same gcc version under Linux 2.2.10) does a
-O1 clean-compile in 3:28.
Maybe the SMP overhead is eating up the missing cycles. You
would like a parallelized make to outperform me again - no?

Lamar, shouldn't you run at least the regression suite too
before building the rpm's?
