Description:
------------
The Return Values of the gmp_testbit() function reads:

Returns TRUE on success or FALSE on failure.

Judging by the examples, that is incorrect. The function seems to return TRUE if the tested bit is 1, and FALSE if it is 0.

(It is a bit of a stretch to consider a failure for a number to have a bit set to zero in the given position.)
