This has been resolved, but one point of my previous recent emails to
the list is that the benefits excluded by silly options like C have to
weighed against the potential reduced portability of other options.

configure_at has a check for the compiler version for gleap;
it has been set at 3.1 because until march 26, 2009, 3.1 worked for us.
Now 3.3 no longer builds sleap.
Wei and Dave may want to update their bugzilla login names, which
