Oh yes, it is...

Ok, but actually I'd like to keep it turned on for other files. In other compilers there's a possibility with #pragma. But I haven't found out whether that's possible with gcc, too.

gcc does not support any sort of #pragma or _Pragma or attribute to
disable specific warnings.  However, there is some ongoing work to
implement this in a future (post 4.2) release.

As an alternative, GNU make has target specific variables so you can  
have that flag set for particular object files and not for others.   
They are pretty easy to use.
