Re: Emacs 21.3.50.1 (CVS sources) MacOS X tex-mode bug

[Steven Tamm]

Darn.  I forgot that 10.2 and 10.3 are still binary compatible (unlike 
10.1).  Are pty's still broken on 10.2.8?  In any case it makes sense 
to have it be #ifdef DARWIN.

I'd also suggest that we have a "darwin-kernel-release" variable 
defined only with system-type darwin and place it someplace like 
sysdep.c or editfns.c.  Should this, perhaps be a built-in variable 
across all *nix platforms?  Something similar to 
get_emacs_configuration in w32.c?
