With this version, using off_t is no longer a problem, however based on the
new compilation error it appears that for Windows, off_t is a 32-bit type
while size_t is a 64-bit type:

../lib/eal/windows/eal_memory.c:519:37: error: shift count >= width of
type [-Werror,-Wshift-count-overflow]
DWORD offset_high = (DWORD)(offset >> 32);
^  ~~

So the options seem to be to either use uint64_t for the offset parameter
as in patch v3, or else introduce something like:
     typedef uint64_t rte_off_t;

Thoughts/opinions?
