In my tests, g++ (either 2.95 or snapshot) does not reject
__FUNCTION__ even with an explicit -pedantic.  This is wrong.
__FUNCTION__ and __PRETTY_FUNCTION__ are GNU extensions, and as such
g++ should reject them in pedantic mode.

__file__ is not and has never been a predefined identifier/macro.
__FILE__ should work just fine.  You might be thinking of __func__,
which is in the new C standard but not in the C++ standard (although
the next C++ standard will probably add it).  Both 2.95 and snapshot
g++ accept __func__, again, without complaint even with -pedantic.
