Bugs in dlls/wsock32/socket.c

dlls/wsock32/socket.c has the following code:
DWORD routeTableSize, numRoutes, ndx, ret;
numRoutes = min(routeTableSize - sizeof(MIB_IPFORWARDTABLE),
0) / sizeof(MIB_IPFORWARDROW) + 1;
The problem here is that both routeTableSize and sizeof(...) are of an
unsigned type, so their difference is also unsigned. Which means that
the minimum between that difference and 0 always will be 0, the result
of the division will thus always be zero, and the result of the entire
expressions is a constant 1.
I have a hunch this is not the intendend purpose of this code, is it?
