Those all seem to be okay.

The r.out.* programs don't use file positioning at all, r.in.arc uses
fseek() with a zero offset, and r.in.ascii always uses reasonably
small offsets (either relative seeks of one or two rows of data or
absolute seeks near the beginning of the file).

I've committed the changes to CVS.
