Unresolved externals when compiling EMACS with GCC.

[Chip Salzenberg]

According to ronald at robobar.co.uk (Ronald S H Khoo):

In March 1989, I posted a pty driver for SCO Xenix.  It's different
from SCO's pty driver because it works -- it knows how to do
non-blocking reads from the master side, so it works with Emacs even
if you don't use select(). I left SCO's ptys as /dev/ttyp? and told
Emacs to use the ones that work, which I named /dev/ttyc?.

The drivers I posted should be available from comp.sources.misc
archives everwhere.
