other related problems. It is a set of routines written in ANSI C and
organized as a callable library.

* A serious bug in the routine glp_del_cols was fixed. Thanks to
Cedric[FR] <fox2113@wanadoo.fr> for the bug report.
* A new advanced API routine glp_mem_limit was added.
* The case GLP_EBOUND was added to the routine lpx_simplex. Thanks to
Cameron Kellough <Cameron.Kellough@sri.com> for the bug report.
* An API routine lpx_write_pb to write the problem instance in OPB
(pseudo boolean) format format was added. Thanks to Oscar Gustafsson
<oscarg@isy.liu.se> for the contribution.
* Two new options --wpb and --wnpb were added to glpsol to write the
problem instance in OPB format.
