Someone is me.  Someone only has a Pentium 133 with 256K L2 cache and
32MB RAM.  Someone is also running KDE/X on this laptop.  

Using egcs 1.1.2 under Linux 2.2.5.(RedHat 6.0).

You have a machine that is 5 times faster than mine.  Also, this is more
than a compile -- this is a whole sequence of events -- cleaning out the
old build directory, unpacking the tarball, applying patches,
configure;make;make install, some other sequences of events, and then
cpio'ing and compressing to build several rpm's.  So, about two thirds
of the time is actually spent compiling, which is still a little slow
compared to your result.

If my machine compiled PostgreSQL as fast as yours, I'd be one happy
camper!
