No this is no problem.
For pathconf(), the path argument points to the pathname of a file
or directory.
IMHO lstat can dedect this case.
Where is the problem ?
Calling pathconf with a symlink is not defined. I suggest
an implementation of "yankee doodle" for that case.
Anyway the broken SuS standard wants that pathconf follow symlinks.
Or how do you interpret this:
[ELOOP]
Too many symbolic links were encountered in resolving path.
But Alan's case "out of filedescriptor" fully counts.
Anyway, I personally would ignore it, but I agree, it's a completely
valid argument.
