History
jdp ab0e664bd0 Fix a range checking bug in ng_int32_parse which affected 64-bit 
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.
