I've got following namespace collision with gcc trunk rev. 142220.
It works for gcc <= 4.3 and trunk rev. <= 142038.
$ gcc-4.4 -c tst.c
tst.c:8: error: declaration of 'static __number
_Numeric_limits_base<__number>::min()'
tst.c:2: error: changes meaning of 'min' from 'const _Tp& min(const _Tp&, const
_Tp&)'
Exit 1
// source:
template <class _Tp>
inline const _Tp& (min)(const _Tp& __a, const _Tp& __b) { return __b < __a ?
__b : __a; }
template <class __number>
class _Numeric_limits_base {
public:
static __number ( min)() { return __number(); }
};
