Follow-up Comment #12, bug #26273 (project lwip):

Whether or not the compiler chooses to do inline copying or a call to memcpy
for structures is presumably a heuristic of the compiler.

For example, the ARM tools will look for structures less than 64 bytes and a
multiple of 4 long and that are word aligned and convert to load/store


Don't change the code to work around compiler faults, but do change to code
for less ambiguous C.
