Summary:  strtol() return wrong value in the underflow case

Original Submission:  This is very old bug.
strtol() must return LONG_MIN for inputs too small.
Original Berkeley version do it.  But avr-libc's version, for example, 
"-5000000000" --> -705032704 (simulavr, avr-gcc 3.3.4). You can reproduce such 
result on any 32-bit computer.

The reason is the attemption to negative LONG_MIN value (0x80000000).
Attached patch correct this mistake. (And it excude compiler warnings in 
comparison).
