Defect in XBD <unistd.h>

[yyyyyyy@xxxxxxxxxx]

        Defect report from : Ulrich Drepper , Red Hat, Inc.

(Please direct followup comments direct to yyyyyyyyyyyyyy@xxxxxxxxxxxxx)

@ page 403 line 14261f section <unistd.h> objection {ud-10}

Problem:

Defect code :  1. Error

Similar to the _POSIX_NO_TRUNC and _XOPEN_ENH_I18N reports.

For _XOPEN_SHM the requirement is also to be != -1 all the time.  All the 
requirement adds is that systems without support for this option must define it 
to zero and have getconf() return a negative answer.

Action:

If the functionality is indeed required for all implementations replace

  other than -1

with

  greater than 0


Otherwise remove the whole sentence.
