Thanks for the report.
IMHO, this is not a bug, and no program should check errno after readdir.
Does EMC's opendir succeed for a directory even though one has
insufficient permission? POSIX requires that opendir fail with EACCES if
``Search permission is denied for the component of the path
prefix of dirname or read permission is denied for dirname.''
If so, I suggest that you file a bug report with EMC.
Maybe they've already fixed it in a newer release.
The only way I would even consider adding code to handle
such a case would be if someone wrote an opendir wrapper
(to be used only on such losing systems) that made opendir
work properly for the case(s) that EMC's implementation
gets wrong. Of course, to go along with the wrapper, there'd
have to be an autoconf macro (probably using AC_RUN_IFELSE) to
detect whether to use the wrapper.
How motivated are you?
