I think I needed this to make my partial build use the same directory as
my fastdebug_build full build.

I only build parts of awt and swing so maybe I've been lucky.  In any
event I made that change.

Do I need to change something?

Rebuilding after tweaking awt_Component.cpp worked fine without this. 
I'll report back at some other time after doing a full rebuild.

64 bit Windows 7

I have Norton 360 and for a full build I disable auto-protect.  I don't
bother disabling that for a partial build.

1.7.0 (I dropped back from using 1.7.9 and so far this has been working,
but I haven't done enough full builds yet to be sure.)
