# [PATCH] git: make was_alias and done_help non-static 3 messages from 2015-03-02 to 2015-03-03. Participants: Alexander Kuleshov, Jeff King, Stefan Näwe.

'done_help' variable does not need to be static variable too if we'll move it out the loop. So these variables do not need to be static.

And I think there is no need for was_alias to go outside the loop, right? > startup_info = &git_startup_info; > > @@ -681,8 +682,6 @@ int main(int argc, char **av) > setup_path(); > > while (1) { > - static int done_help = 0; > - static int was_alias = 0; > was_alias = run_argv(&argc, &argv); Dropping the initialization of was_alias is fine, since we always assign to it before reading. That becomes more obvious if we leave it in the loop, and we can even assign in its declaration.
