[users@httpd] Alias not matching warning

[Kvetch <kvetch@xxxxxxxxx>]

Hello, I just upgraded from Apache 2.0.49 to Apache 2.0.54.  I have a ton of virtual hosts in my conf and now when I start Apache I get a million warning messages stating 
[warn] The Alias directive in /usr/local/apache2.0.54/conf/httpd.conf at line 3267 will probably never match because it overlaps an earlier Alias.

My questions are - is this warning new because I can put my 2.0.49 conf in the 2.0.54 install and still get the warnings.  Did these overlapping Aliases ever work?  I am guessing they did not but Apache 2.0.49 didn't warn me about it.  Is this a new warning in the 
2.05x versions?  Is there a way to get an overlapping Alias to work in a VHost with a different domain name?  If I have domain A with an Alias /test to /01/test1 and then domain B with an Alias /test /01/test2, does domain B's Alias to /test go to /01/test?

Thanks,
Nick
