"enum" is a reserved keyword in java1.5

As a workaround, I added two source="1.5" attributes to <javac ...>
elements, one each in java/resolver.xml and java/which.xml.

I'd submit a patch to rename the variables to a more suitable name,
but I'm walking my first steps in the whole Java world; I'd rather let
others do it.

[PS: mind CC'ing me? I'm hardly pressed to find the time to keep up
with existing subscriptions; I'd prefer not have to subscribe to this
one too]

Thanks,
