perl 5.003_05: lib/AnyDBM_File.pm
AnyDBM_File (modifying ISA does not work as expected)
Now behaves as documented: Modifying ISA works to select
order in which *DB* modules are tried. The default is still
the same.
Add helpful "die" message to end of AnyDBM_File. Previously
it would return a 0, and the failure would eventually show up
somewhere else in the script and be hard to track down. It is
a failure if perl can't open AnyDBM_File. The test regression
suite is supposed to indicate this as a failure too.
