This fixes the "Unknown parameter for tags/attrs" build error.

Fix build with GCC 4.6.
* 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 #.
