The most close thing you can do by now (AFAIK) is compiling as is. If
you have no syntax errors, then the code *will* be effectively compiled
and passed to the linkey, which will most likely complain about not
being able to find '_main'. Any unreferenced thing other than that is
what you want ;) TO get them to a file use DJ's 'redir', I think the
command line is 'redir -e file gcc ....'... note I use -e (it's stderr,
I think) because gcc writes errors to stderr rather to stdout, so you
can't use standard DOS piping (ie. gcc ... > myfile)
