     Catch more strtol() failures when using KEYRINGs
     
-    When parsing what should be a UID while resolving a KEYRING ccache name,
-    don't just depend on strtol() to set errno when the residual that we
-    pass to it can't be parsed as a number.  In addition to checking errno,
-    pass in and check the value of an "endptr".
