Is it possible to get GRASS compiled for CYGWIN with large file support?
I'm doing a v.to.rast that seems to be choking (the output is almost
certainly bigger than 4gb -- the number of cells is being reported as
negative). Is the cygwin binary release not compiled with 64-bit file i/o?
Is it even possible on a Windows box? Thanks!

I suggest to use 6.1-CVS (not 6.0.1) for LFS which contains tests for LFS
in 'configure' and also a flag to enable it:
./configure --help | grep LFS
--enable-largefile enable support for large files (LFS)
The INSTALL file in the 6.1-CVS source code contains a section:
(J) LARGE FILE SUPPORT (for raster maps)
which may be helpful.
