I got a strange message while compiling a routine the other day and was
wondering if anyone could explain its meaning.

On an AT&T 3B1 (unix-pc) running SYS-V I issued a "make all" command which
generated the following compiler directive from "make" (shown broken across
two lines for readability):

        /bin/cc -c -O -I../hdrs -Doptional_arg=optarg -Dopt_index=optind \
					-Dget_options=getopt  newalias.c


The compiler ran for a time and then the following message was generates:

	$! nulled, predecessor circle

The compile finished without further event and "make" went on to complete the
remainder of its work.  The program loaded and worked properly.

The "$!" in the message seemed indicative of "make" but I find no reference
to a $! variable in my copy of the "make" documentation - so I have assumed
that the message was generated by the compiler.

Any ideas as to what this message means?  Thanks.
