Subject: GNU emacs?; more 486/33 info

Anybody working on GNU emacs?  "em" is passable, but I'd like the real

In other news, I have now been able to observe program execution speed
differences when I toggle the Turbo switch (easiest to observe by
scrolling lots of text on the console).  So it's probably some sort of
timing glitch that prevents booting at full-speed?

I finished my hacks on Emacs 18.57 for Linux 0.12.

Patches are in  The README
that you find there is appended below.

As noted by Simon Marlow, emacs trusts the tty driver to set the
input/output speed properly;  by default, the speeds are set to zero by
the kernel.  This affects incremental search (makes it go into
"slow-display optimized" mode); to fix it, set your terminal speed with
stty to something appropriate like 9600.


EMACS 18.57 patches for Linux 0.12:

These patches are in two parts:

1) two small kernel patches to fix some minor problems (fs-diff):
        select.c: a pipe with no writer should select as readable to
                  allow detection of EOF
                  also, the kernel now silently corrects any attempts to
                  select more file descriptors than are supported (this
                  avoids the bit loss on left shift problem reported on
                  the activists list)

        pipe.c: (I sent this to Linus for 0.12, but it didn't make it):
                reads on a pipe should return partial results.
                Otherwise, programs expecting to get such reads will
                work weirdly.

2) patches to the EMACS 18.57 distribution to build it for Linux-0.12.

Shar & enjoy,

John Kohl
