Comment(by hamish):

 AFAICT r.in.bin is the only thing in GRASS 6 which uses G_ftell(), and
 nothing in the grass6-addons repo uses it. It was there in the 6.4.2
 release though, so someone might be using it in a personal addon program.
 Could it harm backwards compatibility to change the function def'n, or
 would it be harmless?

 Seeing that it is only r.in.bin, a less invasive fix to get the 6.4.3
 release out the door might be to add the `#ifdef HAVE_FSEEKO` test into
 r.in.bin directly and avoid using G_ftell() altogether.
