Vladimir,

Thanks for fixing this.

What was it about the template version of method_compartor() that made 
vs2003 generate incorrect optimized code? I just want to make sure I 
don't add more templates with the same issue.

Also, how long will we be supporting vs2003? I was under the impression 
that we had switched to vs2010 even for JDK6. Clearly I was wrong. Does 
that mean that we will keep vs2003 for the duration of JDK6 and thus 
implicitly have that as a build requirement for JDK7 as long as we are 
using the express model?

Bengt
