unix98 pty patch (again)
I've been using this patch for unix98 ptys. Would you guys like to
include this? Do you think it needs to be modified before it will be
accepted?
As far as I know, it should work correctly on all systems.
If (glibc > 2.0) {
if (kernel support for pty98)
getpt should work
else
glibc should emulate with old pty behaviour
// or so I'm told
else
doesn't do anything
