Not exactly IEEE floats, but some kind of float. Emacs 20.7 won't build
out of the box on my vax:

leonide:/usr/pkgsrc/editors/emacs # make
./temacs -batch -l loadup dump
Loading loadup (source)...
Using load-path (/usr/tmp/editors/emacs/work/emacs-20.7/lisp)

Apparently it's possible to turn off float support for Emacs, but in my
distribution, LISP_FLOAT_TYPE is hard-wired to "yes" in the configure

OK, so you might argue why anyone would want to have Emacs in the first
place, but ...

There is, however, a strange, musty smell in the air that reminds me of
something...hmm...yes...I've got it...there's a VMS nearby, or I'm a Blit.
