what is the signed int crc32 value of 0 becuase apparently its ment to be -186917087 but i seem to get 4108050209, i have tried crc32 and int crc32 and they both give me that same result, is the signed int crc32 value somethign different?????

This are both the same Vaues
printf("signed: %d, unsigned: %u",0x0F4DBDF21,0x0F4DBDF21);
output:
signed: -186917087, unsigned: 4108050209

any idea on how to get them signed in perl????
