Hi guilers,

I've accidentally sent the message to guile-devel instead
of bug-guile.  The bug report is forwarded here.

[-- Attachment #3.1.1.2: Forwarded message — Some non-standard O_* flags are missing --]
[-- Type: message/rfc822, Size: 1619 bytes --]

[-- Attachment #3.1.1.2.1.1: Type: text/plain, Size: 654 bytes --]

Hi guilers,

I noticed the following open flags are not defined:
O_NOFOLLOW, O_TMPFILE, O_IGNORE_CTTY, O_NOLINK,
O_SHLOCK, O_EXLOCK, O_ASYNC, O_NOATIME.

Some of these are Hurd-specific, Linux-specific
and BSD-specific.  I'm particularily interested
in O_NOFOLLOW, O_TMPFILE, O_IGNORE_CTTY, O_NOLINK
and O_NOATIME, the others don't matter for me,
though they may be useful for others.

Could extra O_* flags be exported to Guile (in libguile/filesys.c)
on systems where they are defined?

Greetings,
Maxime
