I've just tried configuring with --pdump, and it worked. Of course,
the build process failed because make expected to see an `xemacs'
executable after dumping, but that's OK.
I tried running `./src/temacs', and I got a working XEmacs. Wow.
Almost unbelievable. :-)
BTW, I notice that the hash-tables are "reorganized" after the
undumping. Why is that?
