Well, I was right in that I may be wrong.

Jonathan Shopiro (AT&T Bell Labs) suggested that I try to compile the
following program with the Objective-C compiler and figure out where
the error message comes from.

-------------------------------
int	f();

main()
{
	int	i = f;
}
-------------------------------

I tried it and determined that the Objective-C compiler has nothing bad
to say about this program.  It appears to pass it through (and prepends
some header stuff on the front).  The C compiler of course complains
about the assignment statement.

So my previous statement that the Objective-C compiler 'compiles'
ordinary C code in an Objective-C program was wrong.  Thats what I
get for making claims without fully verifying them first.
