The problem with readdir01 is that it isn't checking the return value of 
readdir().  Minor bug, all it's doing is checking errno.  readdir() passed, 
but errno is 22 from the call to sigaction in tst_sig.c.  I'm not really sure 
why it's having a problem with those three signals, but the really odd thing 
here is that the glibc in turbolinux is returning errno=0 even though 
sigaction is failing with an invalid signal.  The glibc on rh and suse is 
newer though, so it could be something that just got fixed in these newer 
versions.
