Yes, this is what I'm trying to say. But if you saw my libxine's
config.log, there is a check in its configure script for presence of
_environ variable, which is not present in 7.0-RELEASE at least. So,
I'm wondering, why no one else received this error while building
libxine port.

nop, that is just a simple test case, and my aim of assigning NULL to
force compiler to generate code referencing 'environ' variable.

So, should I file a PR for this ?

Thanks for the reply,
