Patch applied, but it's still a strange thing.

I can't reproduce it under RH 6.2. Generally the fix isn't supposed to
do anything (since arg is a double, 10 should be converted to a double
automatically), but the fix can't hurt anything so if it works around a
compiler bug, it's fine.
PHP cannot use sprintf() because sprintf() works with C types with
predefined types for the arguments, whether PHP has its own types, and
autoconverts arguments to match the format string.

<?php
printf('%.2f',0.09999999999999999167332731531132594682276248931884765625);
?>
produces '0.0:' instead of '0.10'
I'm really curious as to why PHP just doesn't use libc's sprintf().

This is not exactly a fix...
