Hi Jim,

You didn't attach a patch to your message, but I guess you want to
remove this case from from the _MD_unix_map_connect_error() function
in unix_errors.c, right?

531         case EACCES:
532             prError = PR_ADDRESS_NOT_SUPPORTED_ERROR;
533             break;

In the latest version of the Single Unix Specification, the connect()
man page says EACCES can only be reported in this case:

    The connect() function may fail if:

    [EACCES]Search permission is denied for a component of the path
prefix; or write access to the named socket is denied.

So it is more correct to map EACCES to PR_NO_ACCESS_RIGHTS_ERROR. Agreed?
