-/* This file was written by Roderick Schertler <roderick@ibcinc.com>,

-
-   A number of things in the older dgux*.h files don't make sense to me,
-   but since I'm relying on memory and I don't have any older dgux
-   systems installed on which to test changes I'm undoing or fixing them
-   here rather than fixing them at the source. */
-
-/* In dgux.h it says "Can't use sys_signal because then etc/server.c
-   would need sysdep.o." and then it #defines signal() to be
-   berk_signal(), but emacsserver.c does `#undef signal' anyway, so that
-   doesn't make sense.
-
-   Further, sys_signal() in sysdep.c already had a special case for
-   #ifdef DGUX, it called berk_signal() explicitly.  I've removed that
-   special case because it also didn't make sense:  All versions of dgux
-   which the dgux*.h headers take into account have POSIX signals
-   (POSIX_SIGNALS is #defined in dgux.h).  The comments in sys_signal()
-   even acknowledged this (saying that the special berk_signal() case
-   wasn't really necessary), they said that sys_signal() was using
-   berk_signal() instead of sigaction() for efficiency.  Since both give
-   reliable signals neither has to be invoked within the handler.  If
-   the efficiency that the comments were talking about is the overhead
-   of setting up the sigaction struct rather than just passing the
-   function pointer in (which is the only efficiency I can think of)
-   then that's a needless optimization, the Emacs sources do better
-   without the special case.
-
-   The following definition will prevent dgux.h from re-defining
-   signal().  I can't just say `#undef signal' after including dgux.h
-   because signal() is already a macro, defined in <sys/signal.h>, and
-   the original definition would be lost. */
