I see one difference.  It's in the return type of the definition vs. the
declaration.  The declaration uses "boost::basic_format< Ch, Tr, Alloc
>::size_type" while the definition's return type doesn't have the "boost::"
namespace prefix.  I haven't looked at the source of Format, so I don't know
where the difference comes from, or why it's fatal.  Maybe it's lookup
problems.  Maybe STLPort actually has an item named "basic_format"?
