Ah, well, it also specifies that the type is bool, not some enum, and since
MSVC doesn't support inline integer static class constants a compromise had
to be made.

On the other hand, I would agree that the compromise chosen for the STLport
is much less useful than the one chosen for MSVC's library.

Boris, do you think this could be changed?
