Re: [Bug-glpk] Please add extern "C"

If you are using glpk routines in a C++ program, you need to
explicitly specify the C linkage as follows:

extern "C" {
#include "glpk.h"
}

This is intentionally not included in the header glpk.h because glpk
being entirely written in C can be compiled by a pure C compiler which
knows nothing about extern "C".
