I've used
ftp://gcc.gnu.org/pub/gcc/snapshots/4.1-20070416/gcc-core-4.1-20070416.tar.bz2
ftp://gcc.gnu.org/pub/gcc/snapshots/4.1-20070416/gcc-g++-4.1-20070416.tar.bz2

In the attachment there is a quick&dirty alpha patch that i don't known
why the gcc compiler says "gcc: unrecognized option '-html'". ???
I don't known where to modify the gcc code to add an option.

The XHTML format to fputs is a little bad.

There are examples to test too.

The idea is to filter the output stream.

Bye, i'm not an expert, i'm a novice, i've not much time :s i'm busy
