(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.

Hi all,
    I wonder if there is some option/flag I can feed to gcc to avoid
that  it continues compiling my source files after it encounters the
first error... I've searched in gcc docs without success.

This is very annoying when e.g. the first error is due to not finding a
required header file: after that gcc goes on and spits out tons of
errors about missing declarations for those things which are declared in
  the not-found header file.

btw stopping on the first error is the default behaviour of many other
compilers (e.g. M$, borland, watcom compilers on win32)...

Thanks,
Francesco
