The whole thing has been proposed before and rejected before.
The patch as given merely renames some random identifiers that happen to
be keywords in some non-C language (thereby breaking not only a lot of
core backend code, which we can fix, but who knows what other
user-written extensions that we can't fix so easily). The *real*
problem here is that to make this useful, we have to buy into the
assumption that C++ should work in the backend. The error handling
assumptions are completely incompatible (setjmp and throw do not usually
interoperate), and there are a lot of other bits of infrastructure that
C++ expects that are not likely to be in a C-based executable either.
I might be willing to accept this patch if I thought it were the end of
the story, but I know that it is only the camel's nose poking under the
tent.
