bpo-11566: Extension build errors on Windows for _hypot (GH-11283) 

This addresses C extension build errors related to an undefined _hypot
symbol when building with the Microsoft Visual C++ Compiler for Python
2.7 [1] or MinGWPy [2]. It also addresses errors when building a C++
extension with MinGWPy and C++11 from cmath, 'error "::hypot' has not
been declared'
