[petsc-dev] Clang configure

[Satish Balay]

Which clang? log?

I don't see this problem with:

$ clang --version
clang version 3.7.0 (tags/RELEASE_370/final)
Target: x86_64-redhat-linux-gnu
Thread model: posix

However - I do get a bunch of plex warnings though. Attaching make.log

If -Qunused-arguments is required - perhaps it can go into the defaults in compilerOptions.py?
