# this was protected for xmingw32, find out why
# stack protection tends to cause segfaults in the generated binary
# occuring in the standard library under msys2 and related compilers.
#
# it's easily shown by simply creating a local std::string. rather than
# get to the root cause we just disable the protection under windows.
