David and Gaby have reported large (outrageous?) bootstrap times on
sparc solaris for 3.2, which I, for one, am not seeing. For example,
on a 4-processor 500 MHz UltraII with 4 GB of memory, here are the
file times for a build of 3.2, even with checking enabled:
banach-383% ls -lrt
total 8475

So it's less than 6 hours, make bootstrap and make check, with libgcj, witout
ada. That's slow (enable-checking accounts for about an hour of it), but
I doubt that sparc linux could do it 20 times faster.
