There are several workarounds in the GCC testsuite for things that could
be better handled in DejaGnu if the next release of GCC could require a
new DejaGnu version.  That might be the right thing to do for GCC 4.1.
Ben Elliston is the DejaGnu maintainer; he's expressed interest in the
past in modifying DejaGnu to support GCC's needs.
