Dear friends, if I run GPC on a 64 bit machine (an AMD Athlon 64 X2 ), it is supposed to produce 64-bit code, is it right? But what are then the sizes of the various integer types available in GPC? If I let this code program sizes; begin writeln ('# size of integer is = ', sizeof (integer) ); writeln ('# size of medint is = ', sizeof (medint) ); writeln ('# size of longint is = ', sizeof (longint) ); end. print them out, I get these results: # size of integer is = 8 # size of medint is = 8 # size of longint is = 8 is that right? Shouldn't it be like 4,8,16?
