Hello Kevin, see http://en.wikibooks.org/wiki/GLPK/Steps_of_GMPL_File_Processing#Prescribed_starts
With glpsol you cannot specify a starting solution. Using the library this is possible. Specify a callback function in glp_iocp->cb_func when calling glp_intopt. Provide the starting solution when glp_ios_reason returns GLP_IHEUR for the first time.
