[PPL-devel] Inclusion of gprolog.h causes severe namespace pollution

[Roberto Bagnara]

Hi there,

gprolog.h defines macros such as

#define B                       (((WamWordP *) reg_bank)[NB_OF_X_REGS+0])
#define H                       (((WamWordP *) reg_bank)[NB_OF_X_REGS+1])
#define CP                      (((WamCont  *) reg_bank)[NB_OF_X_REGS+3])
#define E                       (((WamWordP *) reg_bank)[NB_OF_X_REGS+4])
#define CS                      (((WamWordP *) reg_bank)[NB_OF_X_REGS+5])
#define S                       (((WamWordP *) reg_bank)[NB_OF_X_REGS+6])
#define STAMP                   (((WamWord  *) reg_bank)[NB_OF_X_REGS+7])

which then remain in the namespace.  The probability of conclict
with user's code is quite high, and I have been bitten a couple
of times already.  Can something be done about that?
All the best,

      Roberto
