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?
