Actually, __FUNCTION__ is gcc-specific, while __func__ is the more
portable C99 construct (we #define __FUNCTION__ __func__ in internal.h,
and rely on the gnulib module for __func__, so either spelling works
with equal portability from within libvirt; meanwhile, we should
probably be gradually getting rid of __FUNCTION__).

ACK.
