I still am looking for information on the C compiler. So far, I have seen
three documents:

The v7 documentation has within it a single page detailing some recent
changes to C.

The 4.1 bsd documentation has, hidden within it, some recent changes to
the compiler listed.

I also have seen a BTL memo discussing (at greater length than either
of the above) recent changes to C.

My problem is that none of them seem to agree. Each one of them mentions
changes that the others don't. Also some things seem to work on 4.1 bsd
(what I'm currently running under) that are not mentioned in the
documentation.

I would like to know if there is a standard set of additions to the
language that should be portable across C systems. I am especially
interested in porting from 4.1 bsd to BTL UNIX, as I must do so
in a few weeks. Also, the v7 sheet is dated 1978 and the BTL memo
(3621-791002.02TM) is dated 1979. Have any changes been made since?

Please respond via mail.
Thanks in advance,
