FWIW, I just did a "make world" to find out how long it would take on FreeBSD,
which includes Perl, TCL, building the entire directory tree from
scratch (the entire FBSD environment).

My machine is a P6DNE (with one proc) 256K, 233 MHz, 80MB Ram (part of it is
EDO.)  The target disk is a slow 5400 SCSI drive, the build drives (src/obj)
are IDE.  The OS is FreeBSD-current EXACTLY as in the tree as of
the beginning time of the build.  The 86% CPU really bugs me. Does anyone
know if our make -j X works on the FreeBSD-current build?  Also, I haven't
re-committed our vfork improvement yet, but I can't see that would make
more than a few second difference at most.

CFLAGS= -O -malign-loops=0 -malign-jumps=2 -malign-functions=2 -pipe
