I noticed that, even in Octave 3.4, the included version of GLPKMEX is fairly old and binary problems cannot be handled directly from glpk (using the "B" type variable). Not the end of the world, but are there any plans to update __glpk__.cc to the latest glpkcc.cpp in GLPKMEX 2.8? I diffed the two files, the required changes seem to be fairly marginal at a first skim, but I don't think I have the rights to distribute a modified file. Is anybody working on this?
