You should be able to, they are both squirrel mail and drupal are gpl,
and you will be compiling with the terms of the licence in that you have
to distribute the source with the product.

The only thing I am not sure about but I think will be a problem is that
you have to keep the copyright messages in tack, but because you are
only taking snippets you may need to transfer the copyright messages.
