On LLP64 systems (like 64-bit Windows) long is 32 bits while pointers
are 64 bits, which results in a warning similar to the following:
warning C4244: 'return': conversion from '__int64' to 'long', possible loss of
data
for HAVE_STACK_GROWS_UPWARDS. Fix this by using the ptrdiff_t type
introduced by C99 for this purpose.
