Single quote around double quote mysql string breaks on OpenVMS HP-PHP

[WillemGrooters]

For having Wordpress run under OpenVMS, I would like to suggest a change to classes.php. lines 600-616:
These lines contain a mixture of single and double quotes that the HP-PHP engine cannot handle. It's the only place where strings are delimited by single quotes, and values with double, like this (line 600)

if ( $this->is_attachment ) {
$where .= ' AND (post_status = "attachment")';

This causes errors in accessing MySQL via PHP; the very same problem arises when the SQL-command is issues within PHPMyAdmin, though MYSQL itself has no trouble with it.

If this is changed so strings are delimited by double quotes and the values with single:

if ( $this->is_attachment ) {
$where .= " AND (post_status = 'attachment')";

the problems are over.
Secondly, this is more consistent to the rest of the code, for what I have examined.

Hi Willem, thank you for participating in WordPress!

"Proposed change" is a really lousy bug Summary.

Next time please attach a patch (preferably also against trunk). I am working on patch now.

Problem does not exist in trunk, function is now in wp-includes/query.php and looks like the quotes have been fixed.

No milestone 2.0.6, putting ms to 2.0.5 for now.

Attaching again b/c .txt don't get the fancy diff when viewing attach

(In [4493]) Quote strings in SQL with single quotes instead of double quotes to be more correct and consistent. Props WillemGrooters. fixes #3367
