Summary: /dev/ptmx support for ptys (cygwin)

Initial Comment:
On Cygwin (and I believe Solaris, but I'm not sure), ptys 
are allocated using /dev/ptmx.  This patch checks 
for /dev/ptmx, and if it exists and openpty and _getpty 
don't, it will open ptys using /dev/ptmx.

I took a look at the other patch, and back at the OpenSSH 
pty code (where I got the idea).  The pushes are in an '#ifndef 
CYGWIN' in OpenSSH, and the ioctl for ttcompant is in 
an '#ifndef _hpux'.  Not changing the SIGCHLD handler didn't 
break the cygwin code, but I doubt adding that would break 
things.  I'll work on combining the two, and upload another 
patch.  I'll also fix the nested #ifs.

How does this compare to #579433, in your opinion?

I like that this patch uses autoconf for ptmx usage, but I 
wonder whether the various pushes are necessary in the 
other patch.

Please use #elif instead of nested #ifs where possible.
