Forcing the C locale disables translation entirely. Asking users to choose 
between translation and proper error reporting is a short term stopgap.

GCC 8 will provide a command line switch to disable the translation of the 
"error: " and "warning: " tags alone. This feature will allow proper errors 
and warnings parsing by QtCreator along with translated messages.

It was also proposed to disable the translation of those two tags with an 
environment variable that can be set by QtCreator before invoking the 
compiler. That idea is compatible with previous gcc versions and it will start 
working when gcc 8 is released.

In the meantime, I disabled the translation of those two keywords in the 
French translation. I'm currently working on the translation for gcc 7 but I 
intent to update older versions too.

This feature is tracked by gcc bug #79423:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79423

The gcc 8 feature won't solve the second problem I reported here. QtCreator 
can't find system include files if gcc is translated.
