Avoid compilation errors in MinGW native builds of GDB
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.
gdb/ChangeLog:
2018-01-27 Eli Zaretskii <eliz@gnu.org>
* python/python-internal.h (_hypot) [__MINGW32__]: Define back to
'hypoth'. This avoids a compilation error.
