we are using GLPK services from a C++ application. After upgrading from GLPK 3.0.6 to GLPK 3.1 we are having compilation problems due to the fact that `class' is a keyword in C++ and so cannot be used as an identifier. The problematic lines in glpk.h are lines 297 and 598, reading

  int class;

and

void lpx_set_class(LPX *lp, int class);

respectively.
