* libLBFGS 1.5:
- Configurable starting index for L1-norm computation. A member
variable lbfgs_parameter_t::orthantwise_start was added to specify
the index number from which the library computes the L1 norm of the
variables.
- Fixed a zero-division error when the initial variables have already
been a minimizer (reported by Takashi Imamichi). In this case, the
library returns LBFGS_ALREADY_MINIMIZED status code.
- Defined LBFGS_SUCCESS status code as zero; removed unused constants,
LBFGSFALSE and LBFGSTRUE.
- Fixed a compile error in an implicit down-cast.
