* This file provides definitions for the glpk mutex handling.
29
* It is needed because with the FEATURE_GLPK_USE_MUTEX_LINAR_PROBLEM_SOLVING
30
* feature the glp library (extern package) linear solver will be used with
31
* a mutex switch, so it can run in treads.
32
* If the glp libary is tread save and FEATURE_GLPK_USE_MUTEX_LINAR_PROBLEM_SOLVING
33
* deactivated this file is obsolete.
