I would say that your compiler does not recognize the "-x c++" option.

WebCore/dom/make_names.pl is calling gcc to process some files. We are
forcing gcc to recognize them as C++ (using -x c++). I think dropping
the '-x' option should work as we just need the C-style
pre-processing. If not, you will need to look at the option you have
to force your gcc to do so or just use g++ directly.

In any case, just tweak this line in WebCore/dom/make_name.pl:

my $preprocessor = "/usr/bin/gcc -E -P -x c++";
