Description:
------------
In PHP5, is_a is deprecated in favor of instanceof. Under many configurations, users of PEAR DB will see the following warning:

is_a(): Deprecated. Please use the instanceof operator in DB-1.7.6/DB.php at line 590

Patch below. There's probably a better way of testing the version, but this does seem to work.

Test script:
---------------
Index: DB.php

function isError($value)
{
- return is_a($value, 'DB_Error');
+ if (intval(substr(phpversion(), 0, 1)) >= 5) {
+ return ($value instanceof DB_Error);
+ } else {
+ return is_a($value, 'DB_Error');
+ }
}

// }}}

since DB has all sorts of similar warnings poping up in php5 this is somewhat moot. also is_a() will soon be undeprecated.
