------- Comment #10 from pcarlini at suse dot de  2007-03-11 13:14 -------
In c++config we have the below lines, which I never noriced before, I wonder
whether can cause problems given the our current framework (in the future is
another matter...)

Note hovewer, that currently __cplusplus in the official GNU tree at least is
still *1*. Is it possible that only *Gentoo* GCC has an external patch defining
__cplusplus as 199711L???

Paolo.

// Macro used to indicate that the native "C" includes, when compiled
// as "C++", have declarations in namespace std and not the global
// namespace. Note, this is unrelated to possible "C" compatibility
// includes that inject C90/C99 names into the global namespace.
// XXX May not be necessary
#if __cplusplus == 199711L
# define _GLIBCXX_NAMESPACE_C 1
#endif
