Yep, known problems.  If you search the mail archives, you will find
these popping up time and again, since the GCC maintainers took their
attitude.

I would really like to explore the other solution first: namely, to
get the GCC maintainers to refrain from forcing their headers on
compliant libraries.  It is simply _not right_ for a compiler to force
a library to track changes in compiler's configury.  A reasonably
complaint library should be able to proceed with its development
without having to consult the latest GCC CVS tree.

It strikes me that the maintainers should re-read what Richard
Stallman wrote in the thread about strict-aliasing nuisance: that
gratuitously breaking code of compiler's users is not just harsh
policy, it's a policy of being harsh!  And that a maintainer should
adopt a policy of being kind to users, not being harsh.
