However, frankly, I'd seriously recommend that you use a native OS 
install to build the 64-bit JDK for either Windows or Linux.  Even for 
Solaris, where the 32/64 bit libraries and such are very well 
segregated, there's lots to go wrong.

With the proliferation of LiveCD distros out there, if you don't want to 
do an actual install to Hard Drive, you can still do a build when booted 
from LiveCD.
