this broke bootstrap on (at least) i386-pc-solaris2.11 and

Changing the three instances of 0 to 0U seems to fix this.
It broke bootstrap for me on x86_64-linux and i686-linux too.
I've bootstrapped/regtested the following patch on both overnight
and committed to unbreak bootstrap for others.
Apologies everyone. :-(
I did a full build and test on x86_64, but not a bootstrap, and
apparently it was fine with my not-so-new compiler.
