Dear all,
I'm new with lwip. I started including lwip-1.4.0.rc2 in one
of my project for a 16 bits microcontroller (Fujitsu 16LX
series).
I think I have found a problem in ip4_addr_netmask_valid()
function in ip_addr.c module. Take a look at the following
instruction:
for (mask = 1U << 31 ; mask != 0; mask >>= 1) {
The operation 1U << 31 can't be well performed on a 16 bits
processor. It should be (u32_t)1U << 31. What do you think?
