This is the problem with the default C++ library, I believe.
You're right. That works great.
But we like it when things go fast in the default. :) Is there
a bug open to correct this issue in the default C++ library?

Dan, you're absolutely right. This should be changed. Is someone
thinking about the migration issues? From the documentation:
Later versions of the compiler implemented the new language
features. However, in order to maintain binary compatibility
with existing object files, the macros in the libCstd headers
were not modified. As a result, the latest version of libCstd
continues to have some missing functionality and some of the
functions accept a different set of arguments than those that
are specified in the standard.
The libstlport library was introduced in the C++ 5.4 release
and uses all the language features needed by the library. No
functionality in the library is suppressed because of any missing
language features. As a result, the libstlport library conforms
much more closely to the standard than libCstd does.
