Note that the original code was:
A& operator++(void)
{
++n;
if (__builtin_expect(n == m, false))
g();
return *this;
}
but g++ fails to optimize that by decrementing m outside
the loop (so

That never works because it always defines _REENTRANT.
You probably mean:
#ifdef _REENTRANT
#define GCC_BUGFIX 1
#endif
#include
#undef _REENTRANT
#ifdef GCC_BUGFIX
#define _REENTRANT 1
#endif
The drawback of this

If you remove the 'extern', the compiler still crashes:
struct a { int i, j; };
template struct mutex_tct { static a S_mutex; };
template a mutex_tct::S_mutex = {0,1};
template <> a mutex

Sorry, the previous one was compiled with pch.

Ok, thanks Volker. Our last posted crossed, sorry.
I'll close the PR because I suppose you are right.
I want my library to accept (a + b) * c however,
so I guess I'd have to add new operator*

I managed to strip it down to a more reasonable size.

This wording is very boost specific and does not give
a solution for other libraries that need to detect
at prepocessing time whether or not -pthread is
being used.
Consider a library libjohndoe, this library
