Parse Error on activation

Trying to activate the latest dev version I get a

Parse error: syntax error, unexpected T_STRING in /var/www/drupal5/sites/all/modules/sitenotes/sitenotes.install on line 36

The offending line is in uninstall where

// Remove all Site Note blocks.
db_query('DELETE FROM {blocks} WHERE module='sitenotes');

need to be

// Remove all Site Note blocks.
db_query('DELETE FROM {blocks} WHERE module="sitenotes"');

not sure why none has reported this before, but it might have to do with php or mysql version/configuration detecting this although the function isn't called (afaik) during install.
