Description: ASP tags aren't recognized

Ok, I have a workaround, and a related bug fix.
I think the first time I missed an occurrence of asp_tags in zend-scanner.l.
This time I did a global search and replace, and ASP tags started working. phpinfo() still shows that I set the asp_tags flag On, so I don't understand why this made a difference.

Once I got that working, I found a clearer bug: the scanner doesn't support one-line comments in ASP tags.
Even though they're shown in the ASP tags example at
http://www.php.net/manual/language.basic-syntax.php3

Here are the changes I made to get it working:

--- zend-scanner.l 1999/12/30 22:31:18 1.1.1.2
+++ zend-scanner.l 2000/01/01 02:24:16
