Get rid CL_REQUIRE/CL_PROVIDE(cl_F_leastpos), it is not really necessary.

Move static variables least_positive_[SFDL]F into least_positive_LF() function
(which is the only user of those variables) in order to avoid possible static
order initialization problems. While at it, make least_positive_LF() function
static.
