Hi Val, all,
Tested using gcc-4.{6,7}-based toolchain.
My comments inlined.

> * dom/make_names.pl: Execute preprocessor without the -P option. The
> preprocessor in GCC 4.6 eats empty lines, effectively breaking the
> parsing performed by this script. Dropping the -P option when invoking
> the preprocessor keeps the empty lines but as a side-effect also adds
> additional linemarkers.
>
> From the cpp manpage:
>
> -P Inhibit generation of linemarkers in the output from the
> preprocessor. This might be useful when running the preprocessor
> on something that is not C code, and will be sent to a program
> which might be confused by the linemarkers.
>
> The linemarkers are not problematic, however, because the script
> properly handles them by ignoring all lines starting with a #.
