* FD_ISSET requires that the fd being tested is >= 0, so unset fd -1 causes trouble. * Remove code to enable X I/O signal generation from xinit.c If the I/O signals are enabled before the signal handler has been set up, the default action on receipt of a SIGPOLL or SIGIO will be that the program exits. For now, turn the signals off, as they aren't necessary and may not even be an improvement. * Ensure fds are declared as signed and initialized (to -1) The global fds may be accessed from the signal handler before any particular device has been opened. Ensure that the fds are initialized statically and that the value is distinguishable from all valid descriptors. modified: initdsp.c modified: initkbd.c modified: keyevent.c modified: osmsg.c modified: rs232c.c modified: timer.c modified: tty.c

This is the implementation of the Medley Interlisp virtual machine, for a byte-coded Lisp instruction set and some low-level functions for connecting with Lisp for access to display and disk etc.
There are make file fragments that include all the flags and variables you have to set for each hardware/OS target.
- cd to the "bin" directory
- have "." on your PATH
- do "./makeright x"
It will (attempt to) detect the OS-type and cpu-type, and put together the makefile parts that it needs. It will build in ../ostype.cputype-x (for the .o files) and ../ostype.cputype for the executables.
