Description:
------------
Previous bug #51076
http://bugs.php.net/bug.php?id=51076
was fixed by:
svn commit r295225 ( http://svn.php.net/viewvc?view=revision&revision=295225 )

but later, commit r295230 ( http://svn.php.net/viewvc?
view=revision&revision=295230)
updated shtool to version 2.0.8 without backporting the previous patch.
(In upstream, nothing changed regarding mkdir between 2.0.6 and  2.0.8)

And so, the race condition with -j>1 is still there. (In my case, it appeared 
during the "make install" step processing the installation of the extensions)

Error was: "mkdir: cannot create directory ... : File exists"


So, the patch in r295225 should be reapplied to shtool 2.0.8.


In a second time, why not replacing all the mkdir code block of shtool by 
something like:
if opt_p = no:
   mkdir ...
   chmod ...
   chown ...
   chgrp ...
   ...
else:
   mkdir -p ...
   chmod -R ...
   chown -R ...
   chgrp -R ...
   ...

That would be safer I think ...

Please do not submit the same bug more than once. An existing
bug report already describes this very problem. Even if you feel
that your issue is somewhat different, the resolution is likely
to be the same. 

Thank you for your interest in PHP.
