 The segment library, managing temporary data stored on disk, does not
 support LFS, although file sizes can easily break the 2GB boundary. Fixed
 in trunk r39760. All is needed is to add

 #compile if LFS Large File Support present:
 ifneq ($(USE_LARGEFILES),)

 to the Makefile. I have also added checks and warnings if LFS is not
 available but file size would exceed 2GB. In this case it exits with an
 error. Tested on Linux 32 bit (does not apply to Linux 64 bit). Not sure
 if this would be an enhancement or if the segment lib is defect because it
 tries to read/write to temporary files although it can't, lot's of ugly
 warnings that don't help much. Should this change be backported to grass6?
