# The Python developers have chosen to always compile Python with the
# -Wno-strict-aliasing flag set.  If the MP code is compiled with
# strict-aliasing turned on, then at high optimization levels we can
# get GCC warnings about the mere use of Python objects like Py_True
# and Py_False.  This unfortunately means that we must set the
# -Wno-strict-aliasing flag for MP as well.
#
# Versions of GCC before GCC 3.0 do not support the -Wno-strict-aliasing
# flag, so we test for and only use it with newer GCC versions.
