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' [1] https://www.microsoft.com/en-us/download/details.aspx?id=44266 [2] https://mingwpy.github.io/
