C++ and Ruby developer?
Don't have -pedantic in your ${CXXFLAGS}!
Huge swathes of Ruby Gems with C++ externals fail to build with this flag and it's a swine to fix them all when you're in the middle of a Ruby project.
Example: https://github.com/eventmachine/eventmachine/pull/433
...Or fix them all up and I'll be eternally grateful.
