Subject: realpath no error for unreadable-symlink
Date: Thu, 2 May 2024 08:16:26 +0200

coreutils version: stable 9.5 (bottled)
OS version: macOS 13.6.6 (22G630)

`realpath` doesn’t behave correctly for unreadable symlinks:

wannes <at> Stefans-iMac ~ % ln -s . src        
wannes <at> Stefans-iMac ~ % grealpath -e src/..
/Users
wannes <at> Stefans-iMac ~ % chmod -h 000 src
wannes <at> Stefans-iMac ~ % grealpath -e src/..
/Users/wannes

Expected behaviour:

wannes <at> Stefans-iMac ~ % grealpath -e src/..
grealpath: src/..: Permission denied

Right, looks like we'll have to cater for EACCES on darwin.
I'll have a look
