As we speak, I have LFS 4.0 compiling on a P133 with 192 MB RAM with
of 128MB.  Of course, GCC and Glibc take quite a while.  For Glibc (ch.
it took overnight, so I would guess around 7 or so hours.  For GCC (ch.
without the "--enabled-languages" (building all languages) it took
and then until even noon.  So around 12 or more hours.  If you want to
how your system will do, start in the book, time the compile of Bash,
use the SBU's to figure out roughly how long it will take.  Should not
too bad.

I do not know if it would be much faster on a P200, so I think on the
system would be good.  It just takes a little more time.  :)  My laptop
a 75 Mhz intel proc (and max 20MB RAM) can also compile LFS 4.0, but GCC
And Glibc take around 3 days each!

Hope this helps!
