>Description:
When compiling a program using string::rfind(), the following code from basic_string.tcc is is incorrect :          

basic_string.tcc:630: __pos = std::min(__size - __n ,__pos);
This is resolved into:
__pos = std::((__size - __n) < (__pos) ? (__size-n) : (__pos));

And the compiler choked on __size.
>How-To-Repeat:

>Fix:
__pos = min(__size - __n ,__pos);
Fixes the problem.
