No.

I tried to bootstrap & test the attached, but it fails in libjava:

../../../../../../trunk/libjava/classpath/gnu/java/awt/font/opentype/truetype/TrueTypeScaler.java:0:
internal compiler error: in fold_overflow_warning, at
fold-const.c:1018
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

if we really want to specialize sizetypes, then this would be the way to go
(after making it work, of course).

Richard.
