To be honest, I don't know how valuable it is, or whether or not it
might be in use by someone out there. It could be useful maybe
with libtcc applications to wrap C-code in strings, for example.

Users, as we know, are fully entitled to express their wishes freely
as well as to call a bug whatever gets in their way and not to be
bothered with the details.

But: As soon as someone considers to patch the public TinyCC, he
cannot see himself as an user merely anymore. He is expected to
know what he is doing and to have understood what has been done
before. (The short answer to a "Sometimes Asked Question")
