CASETEK@CRVAX.SRI.COM (04/21/87)
I just installed GNU Emacs (18.41) on a CDC Cyber 910
workstation. This workstation is a member of the Silicon
Graphics series 3000 family. I guessed at some of the
parameters (we just got the machine, I am more used to
Suns and bsd). I am particularly uncertain about the
value of FSCALE.
The following change to sysdep.c was prompted by a compiler
error message.
477c477
< int (*sigio*) ();
---
> int (*sigio) ();
Here is the m-sgi.h file I created. I am posting this to
Info-GNU-Emacs because it is too late to get it into the
Version 18 release.
