Oooh .. yes.

Hm.  Well then this part is not compatible it seems.  I have never
tested it that much, i usually step in when somewhere the build
fails or spits warnings like grazy.  Actually i have given up on
managing the mess that happens from compiler development.

I had instrumented the code this afternoon, but the code generator
would require real brain effort.  The flag is set, but when
actually the warning occurs, i dunno, it is much, much later.
I thought about adding a specific function, you know, like
warnopt() or so, that could check for -Werror -Wno-error=X not
bailing for X, it is really only these places in the generator
which make it weird.

Unfortunately tcc_warning() does not take arguments itself, even
though variable preprocessor arguments where pretty much
widespread already over twenty years ago .. with different syntax.
I also never used it.  It did X((Y)), this could be a solution
here too.  It still does not help for the generator, sadly.

Despite that being too complicated ... ... i have to cook!
