Thanks for this patch. I discussed this with the gnulib folks and Bruno discovered that a number of the gnulib modules that should have been marked as relying on c99, were not so marked. This includes verify (the module that caused GNU make grief). Bruno pushed a patch (to gnulib) which adds c99 prerequisites on the modules that need it. I believe that with this change to gnulib, it's no longer necessary for GNU make to change anything in our configure.am. However I'm not sure the best way to check this. Maybe I can come up with a wrapper script locally that sets the default to c89 on my compiler to ensure that configure will detect this and add appropriate flags.
