dnl| The following info is mostly gathered from GNU Emacs 19.24.  Basically,
dnl| we are trying to find out whether this is a System-V derivative in
dnl| which pipes don't work with select() and if so, whether there is anything
dnl| strange about the way to open a pty.  Some of the work was done above
dnl| by looking for _getpty, grantpt, and getpseudotty.  A few other strange
dnl| properties of particular systems are also handled here.

dnl| 4/6/97 I'm not sure there really are any systems where pipes
dnl| don't work with select(), and ptys cause problems on many
dnl| systems, so I'm changing the default to disable ptys in all
dnl| cases.  I will change it back if I get bug reports that are fixed
dnl| by doing a "configure --enable-ptys"
