machines. The code formerly read:
long val;
if (val < (long)-0x80000000 || ...)
return EINVAL;
The constant 0x80000000 has type unsigned int. The unary `-'
operator does not change the type (or the value, in this case).
Therefore the promotion to long is done by 0-extension, giving
0x0000000080000000 instead of the desired 0xffffffff80000000. I
got rid of the `-' and changed the cast to (int32_t) to give proper
sign-extension on all architectures and to better reflect the fact
that we are range-checking a 32-bit value.
This commit also makes the analogous changes to ng_int{8,16}_parse
for consistency.
