Now mq_unlink("/queue") and unlink("/dev/mqueue/queue") work, thanks!

But there is a regression:
stat() now returns st_mode = 0 for the queue file which results in an 
invalid S_IFMT field:

$ uname -r
3.5.6-1.x86_64

$ stat --printf '0x%04f/%A %n (%F)\n' /dev/mqueue /dev/mqueue/mqtest
0x43ff/drwxrwxrwt /dev/mqueue (directory)
0x0000/?--------- /dev/mqueue/mqtest (weird file)

$ rm -iv /dev/mqueue/mqtest
rm: remove write-protected weird file '/dev/mqueue/mqtest'? y
removed '/dev/mqueue/mqtest'


Previous:

$ uname -r
3.5.5-1.x86_64

$ stat --printf '0x%04f/%A %n (%F)\n' /dev/mqueue /dev/mqueue/mqtest
0x43ff/drwxrwxrwt /dev/mqueue (directory)
0x8180/-rw------- /dev/mqueue/mqtest (regular file)

$ rm -iv /dev/mqueue/mqtest
rm: remove regular file '/dev/mqueue/mqtest'? y
rm: cannot remove '/dev/mqueue/mqtest': Operation not permitted
