4.0.8 stills thinks Linux hasn't /dev/ptmx

4.0.8 stills thinks Linux hasn't /dev/ptmx

[DervishD]

    Hi all :)

    I've downloaded Zsh 4.0.8 and in Src/Modules/zpty.c, /dev/ptmx is
only used if one of __SVR4, sinix or __CYGWIN__ is defined. Under
Linux none of these is defined, but Linux supports PTY multiplexor
since (AFAIK) kernel 2.2. IMHO, since under Linux you can choose
between classic PTY support (/dev/pty??) or PTY multiplexor, the
appropriate thing here should be using configure.

    Anyway I gave more details and a workarount in zsh-workers 19196,
using GLIBC defines for seeing if the system supports ptmx. So, no
configure needed (by now)...

This isn't something we'd fix on 4.0.8, anyway, which is now being
declared dead.  (At least, if 4.0.8 compiles; I'm on holiday after
tomorrow, so it would be a good idea to tell me before.)

It's certainly a possibility for 4.1.  It will required testing for
grantpt, unlockpt and ptsname, which seem to be present but undocumented
(anywhere that I can see), thought chances are they're basically
POSIX-compatible.  So ideally it should be done by someone who knows
what they're doing.

    OK, don't worry because this is not urgent, at least I have the
old mechanism working on Linux (on any Linux, I suppose). This
definitely can wait.

    I haven't build 4.0.8 yet, so I cannot tell if it builds, but
certainly this problem didn't prevent it from building in the past,
so no reason for failing exist now, neither.

    I'm not able to write the autoconf recipes, sorry, and I'm not an
ptmx expert O:), but if I can lend a hand, just tell me.

    Happy holidays :)

anyone know how to get in touch with him or the person/people working on it?
