Thanks for this! I downloaded and recompiled (after a make clean) and it
seems to have worked fine. I also needed this for r.in.arc. I put the code
modifications you made into that make file and it also seems to have worked
fine. I was wondering whether you (plural, ie someone on the development
team) could drop those three lines of code into all the related routines. I
would think they are 



Thanks, Jerry

The --enable-largefile configure option only enables LFS on code which
specifically chooses to use it. As r.out.arc only performs sequential
output, it's safe to enable LFS, so I've modified the Makefile to
enable it.
