"Bug" is a big word, rater nit-picking.

I'm just advocating for use of "!= 0" instead of "-1" in the docs.
As I say the stds only require a return value of "0" for sucess and
different then "0" otherwise.  Since most implementation I've seen do
fsetpos() { return fseek(); }
This is a moot point.  It's just that by reading the Linux man, you would
be tempted to test for error by doing
(fsetpos() == -1)   instead of (fsetpos() != 0)

If you are doing lot of porting, little things like that
can make you loose lot of hair.
But then again, I've never seen such case yet.
