Once you squash all these warnings, you could set up a little bit of Jenkins or Travis CI logic to check for PRs that add new warnings and marks them appropriately. Of course, with people making commits directly to master, warnings introduced by those direct commits will be ascribed to those who make PRs against master. But at least you'd catch them quickly.
The MPICH project has a script that could easily be adapted to extract only the warnings: http://git.mpich.org/mpich.git/blob/HEAD:/maint/clmake.in Alternatively/additionally you could have a build bot that watches for new commits to master, runs a quick build on each new commit, and sends mail to de...@open-mpi.org and the offender with the new warnings that have been introduced. -Dave > On Nov
