#9931: Allocate returned buffer in realpath() in case resolved_name's argument
is
NULL
-------------------------------+---------------------------

Type: enhancement | Status: new
Priority: normal | Milestone: R1
Component: System/libroot.so | Version: R1/alpha4.1
Keywords: realpath | Blocked By:
Blocking: | Has a Patch: 0
Platform: All |
-------------------------------+---------------------------
Add support for NULL as resolved_name argument in realpath as defined in
The Open Group Base Specifications Issue 7 IEEE Std 1003.1, 2013 Edition
(http://pubs.opengroup.org/onlinepubs/9699919799/functions/realpath.html).
In this case, the returned buffer is allocated by realpath and can be
passed to free().
The behavior was only "implementation defined" in previous revision like
The Open Group Base Specifications Issue 6 IEEE Std 1003.1, 2004 Edition
(http://pubs.opengroup.org/onlinepubs/000095399/functions/realpath.html).
Yodl (http://yodl.sourceforge.net/) rely on this behavior in
yodl/src/lexer/lchdir.c.
