To make glpk reentrant you only need to replace two low-level routines
lib_set_ptr and lib_get_ptr in the file glplib1.c. There is the
"pointer" there, which must be stored separately for each thread in
so-called thread local storage (currently it is simply stored in a
static location called "secret place"). Then the entire glpk (except
some routines which still use static data) will be reentrant.
