From perldiag.
Value of %s can be "0"; test with defined()
(W misc) In a conditional expression, you used <HAN-
DLE>, <*> (glob), "each()", or "readdir()" as a
boolean value. Each of these constructs can return a
value of "0"; that would make the conditional expres-
sion false, which is probably not what you intended.
When using these constructs in conditional expres-
sions, test their values with the "defined" operator.
Though it is likely this is a result of Redhat 9 / Unicode damage.
Try setting your LANG to C and see if it works.
