    Avoid compilation errors in MinGW native builds of GDB · b2a426e2

    The error is triggered by including python-internal.h, and the
    error message is:
    
         In file included from d:\usr\lib\gcc\mingw32\6.3.0\include\c++\math.h:36:0,
    	      from build-gnulib/import/math.h:27,
    	      from d:/usr/Python26/include/pyport.h:235,
    	      from d:/usr/Python26/include/Python.h:58,
    	      from python/python-internal.h:94,
    	      from python/py-arch.c:24:
         d:\usr\lib\gcc\mingw32\6.3.0\include\c++\cmath:1157:11: error: '::hypot' has not been declared
            using ::hypot;
    	        ^~~~~
    
    This happens because Python headers define 'hypot' to expand to
    '_hypot' in the Windows builds.

    	* python/python-internal.h (_hypot) [__MINGW32__]: Define back to
    	'hypoth'.  This avoids a compilation error.
