-# TODO: is this still relevant?
-# GCC versions 4.2.x introduced a warning "allocating zero-element array"
-# Allocating zero-element arrays is an allowed if not somewhat dubious
-# technique though, so this warning is plain wrong and has been fixed
-# in gcc 4.3. Unfortunately there is no way at all to suppress this warning.
-# Some files in this directory use zero allocated arrays, we need to
-# disable the WaE mechanism for the GCC 4.2.x series.
