Yet another OpenJDK7/Windows build story

[Jonathan Gibbons]

Raffaello,

As regards being online, you only have to be online if the required 
files are not already available on your system. On subsequent builds, 
you do not need to be online; or you can download the files ahead of 
time and set ALT_DROPS_DIR to the downloaded location.
