This means that it *is* coming from the native compiler's list of
definitions.  In this test you reported:

echo | /usr/bin/c++ -E -dD - | grep GXX_WEAK

try adding "-x c++" to the options to make sure it treats the
translation unit as c++.  Look at the script


in the source tree to see where the native flags get detected.
