Glp_main is a undocumented api routine. It is used just to provide
possibility for building glpsol as a glpk-based application (with make),
because glpsol calls uses internal non-api routines and data structures
not declared in glpk.h.

No memory blocks are lost, however, glp_main assumes that all memory
allocations are performed within it, so if it detects that some blocks
are still allocated on exit, it reports the error.
