(This question is more appropriate for gcc-help, this list is for gcc
development.)

>From the manual page:

      -Wfatal-errors
           This option causes the compiler to abort compilation on the first
           error occurred rather than trying to keep going and printing fur‐
           ther error messages.

Cheers,

Manuel.
