The ARM disallowed conversions in template arguments. The draft standard
allows various conversions. The latest Sun compiler accepts this code.
(See about upgrading your compiler to the 4.1 release.)

Non-type template arguments for template functions are a recent
addition to the language. The current Sun compilers do not support
that feature. The next major release will support them.
