April snapshot tagged

The April snapshot has been tagged.  Binaries will be uploaded soon.

This snapshot includes support for internationalization.  To bootstrap
this, use boot-2010-02-1.lisp.  You may also want to use the -P option
for build.sh so that the pot and po files are updated.  If you want to
update the piglatin translation, you'll need to load tools/piglatin.lisp
and run (do-translations).

Also, a cricital bug in SSE2 has been fixed.  GC hooks that used the
floating-point would corrupt the SSE2 registers and cause computations
to return, essentially, random results.
This didn't affect x87.
