Currently sysdeps/posix/remove.c reads this:
#v+
int
remove (file)
const char *file;
{
/* First try to unlink since this is more frequently the necessary action. */
if (__unlink (file) != 0
/* If it is indeed a directory... */
&& (errno != EISDIR
/* ...try to remove it. */
|| __rmdir (file) != 0))
/* Cannot remove the object for whatever reason. */
return -1;
return 0;
}
#v-
However, POSIX says unlink(2) returns `EPERM' when PATH is a directory. `EISDIR'
is Linux-specific and the "Rationale" section at
http://www.opengroup.org/onlinepubs/9699919799/functions/unlink.html says that
"[a]pplications written for portability to both POSIX.1-2008 and the LSB should
be prepared to handle either error code."
Currently remove(3) fails on GNU/Hurd [0] and GNU/kFreeBSD [1] because of this.
Thus it should be changed to handle both `EPERM' and `EISDIR'.
