OpenOffice2.0 64Bit ready?

[O. Hartmann]

Dear Sirs.
I do not follow up everything written herein, so my question may sound 
stupid.
On my FreeBSD 6.0 AMD64 box I run a 'clean' 64 Bit FreeBSD 6.0 (no 32Bit 
compatibility). I want to use OpenOffice from time to time reading Word 
or Excel documents. Can we compile and run OO 2.0 without 32 Bit 
compatibility enabled? I know this implies 64Bit clean code, so the 
major question would be whether OO 2 is 64 Bit clean or not.

Thanks for your answers,
Oliver
