Linter not showing any issues

Checklist

• [x] Check that you have the GNU C Compiler installed by typing gcc --version into a terminal.
• [x] If you don't have the linter package installed, either update to the latest version of linter-gcc or install linter directly with apm install linter.
• [x] Ensure that you are using a valid grammar - either C/C++/C++14
• [x] Ensure that you have read all the relevant information in the wiki, particularly the Common Issues page.

Issue (including debugging messages):

When copy-pasting the command from the debugging console into terminal, it correctly shows the errors. In Atom no errors are found.

There was an update in Linter that removed the v1 api, but this package (linter-gcc) does not seem to be maintained anymore. Try @tvincent056's fork, linter-gcc2. See comment on #185
