raible@ORVILLE.ARPA (05/01/87)
So the following s-, m-, and diffs should be sufficient to get
a reasonable gnu emacs on a silicon graphics 3.5 machine.
Features: dumps, asynchronous subprocesses with ptys, uses the iris
directory routines and alloca, sockets, select, etc.
Known bugs: - PURESIZE is too big. Anyone know how to read out of the
running emacs how much of PURESIZE was actually used?
- Starting new processes sometimes losses due to (random?)
SIGIOT's. A work-around is included.
- etc/loadst only gets the time - nothing else
- No mouse support (has anyone done this yet?)
Have fun...

This file contains all of the files and changes (relative to v18.41) needed
to bring up gnu emacs on a SGI iris.
In brief, the changes are:
additional header files:
m-irist.h s-iris3-5.h
config.h changed to use the above files

SIGIO can be used only on systems that implement it (4.2 and 4.3).
CBREAK mode has two disadvatages
1) At least in 4.2, it is impossible to handle the Meta key properly.
I hear that in system V this problem does not exist.
2) Control-G causes output to be discarded.
