164 dnl| The following info is mostly gathered from GNU Emacs 19.24. Basically,

167 dnl| strange about the way to open a pty. Some of the work was done above
168 dnl| by looking for _getpty, grantpt, and getpseudotty. A few other strange
169 dnl| properties of particular systems are also handled here.
171 dnl| 4/6/97 I'm not sure there really are any systems where pipes
172 dnl| don't work with select(), and ptys cause problems on many
173 dnl| systems, so I'm changing the default to disable ptys in all
