Re: Future evolution of c++config.h and _GLIBCXX_USE_LONG_LONG

The danger is really on the Libc side. According to the C++ standard, the following program is valid:

#include <iostream>
int main() { return lldiv_t; }


No sane person would do this (other than a test suite writer), but it is valid.

Thanks. Now I begin to really understand what you mean: your message is
actually about the *possible* behavior of a _GLIBCXX_USE_LONG_LONG
macro (etc., as explained by Gaby and Jason), not about the *current* usage of
it...
