Win64 Builds

[David Simcha <dsimcha gmail com>]

I'm running out of memory (or more precisely, address space) trying to 
open very large files in Gnumeric on Windows 7 x64.  My system has 4GB 
of physical RAM, but (probably) due to 32-bit address space limitations 
Gnumeric can only get up to 1 GB and change of memory usage before it 
crashes with an "allocation failed" error message.  (Openoffice.org 
can't handle this file either, and Excel 2007 can barely handle it.)  
Given that one of Gnumeric's niches is its relatively good handling of 
huge spreadsheets, and address space limitations break this, would 
whoever does the Win32 builds also be willing to create a native Win64 
build that doesn't have 32-bit address space limitations?  If not, has 
anyone know if Gnumeric works when large address space aware mode is 
enabled?
