|functions returning int with 'l' protocodes.|
Hello PARI developers, Comparison functions usually return an `int' not a `long'. This is correct since they always returns 0, 1 or -1. However some of them are available from GP, but there is not protoype letter for int, so we use l instead. But this is wrong, since on 64bit mechines, int is 32 bit and long 64bit. On ia64 PARI compiled with gcc -g (for all versions) do not pass the bench, because in some cases, (int) -1 became (long) 2^32-1, which is correct, since we have hid the cast from the compiler. FIx involves either add a new letter code for integers, or `upgrade' all functions return int to long. The second option seems better. Cheers, Bill.
