I'd rather imagine that g++ will invoke cc1 on .c files, unless it
uses different rules for computing the default source language.

But this is exactly the kind of subtle changes I was afraid of.
Without a lot of testing, you cannot be sure the programs behave the
same, and I don't think we can ever invest the resources for such a
massive testing.  If somebody assumed certain features or misfeatures
of the old version to exist, the new one will break their work.
