           Summary: lib/tablegen/TGPreprocessor.h requires NULL, but does
                    not include a header for it
           Product: libraries
           Version: trunk

As in summary, lib/tablegen/TGPreprocessor.h uses NULL, but does not include a
header for it.

At the moment it includes <vector>, which picks up <cstdlib> on many
implementations. In g++, starting with g++4.6, it no longer does, therefore the
following patch (or something similar) is required:
