Contributing to GCC

[Krzesimir Nowak]

Hello.

My name is Krzesimir Nowak and I'd like to try my hand at contributing
to gcc in my free time.

To start learning a workflow I started with something easy - 42014. Is
testcase for this fix necessary (it would be checking preprocessor
output)? Is sending a patch created by "git format-patch" for review
with git-send-email to gcc-patches acceptable (or even better - git
patches with cover letter)?

Thanks.
