Wrong quote style with pdo_informix

Question

I am using PDO_Informix (1.3.0) with a Informix (11) database. However when I use the pdo::quote command the escape of a single quote is wrong (yes I know I should use prepare statements). Pdo::quote escapes a single quote with a backslash like this 'it\'s' while it should escape the single quote with an extra single quote like this 'it''s'. Can I tell the driver to use the proper quoting style?
