Windows issues

[Pepijn Van Eeckhoudt]

I've traced the directory utime issue back to the jnr-posix project 
which is used by JRuby. I've patched the bug and submitted the patch 
back to the JRuby guys. This means we'll have to wait for a new JRuby 
build before this can be resolved from a buildr point of view. Should 
this block the buildr 1.4 release or not?

I've also created a bug in the buildr jira project with the spec patches 
attached. Could someone else give these a try?
