Bug description:  0+0=4G  on aix4.3 (64bits)

Script:
        <?
        echo '0+0=', 0+0, "\n";
        ?>

Output of script on php 4.2.3:

        0+0=4294967294

which is equal to 2^32-2

(Output of script on php 4.1.2 and 4.0.6:
        0+0=4294967296
which is equal to 2^32).

In general, all simple additions and multiplications produce huge
numbers:

        0+0=4294967294
        0+1=4294967295
        1+0=4294967295
        1+1=4294967296
        0-0=0
        0-1=-1
        1-0=1
        1-1=0
        0*0=3.5178585246345E+18
        0*1=3.5178585265101E+18
        1*0=3.5178585265101E+18
        1*1=3.5178585283857E+18
        0/1=0
        1/1=1
        2/1=2
        2/2=1

I don't know if it is very relevant but the rs6000 on which aix4.3 is
running
is a 64bits machine. The c program
        int main()
        {
                printf("long=%dbits\n",8*sizeof(long));
                return 0;
        }
outputs 'long=64bits' when compiled with 'cc -q64', while when compiled
with 'gcc' it outputs 'long=32bits'.

Thanks very much in advance,
Rein van Vliet
