For the latter reason, this bug is not in the realm of GCC, and much
less of g++ or libstdc++.  This issue has to be taken up to system
packagers and POSIX people as they have managed to produce conflicting
requirements leading to fear, uncertainty and doubts about well
thought systems and programs.

And that is a pain in the ass.

I can understand the submitter's frustration.
Personaly, yesterday I wasted time looking for causes of build failure
in the Axiom computer algebra system

     http://www.nongnu.org/axiom/

only to figure out that some glibc-based systems have taken the right
to hijack names in user name space (in my case, some macros "likely"
and "unlikely" were defined!)
