Set gsl_check_range to zero to disable range checking in the static
functions.

Note that there are inline versions of these functions and these are
controlled by the preprocessor definitions GSL_RANGE_CHECK and
HAVE_INLINE.

By default GSL builds using the inline versions internally so calls to
the static functions should be rare.
