Hi Yoshiki, Eliot,
I confirm the problem, 32 bit linux build fails, on x86 too. it appears on
travis log:

Makefile:252: recipe for target 'aio.o' failed


We are doing horrible things with C macro : #define ftell(s) ftello(s)
because ftell is a different function with its own signature.
If we include stdio.h AFTER this macro, then we are causing big trouble
mixing the signatures...
We can cheat as long as we do not get caught... It seems to me that we are
caught red-handed!
Compilation appears to pass on x64 linux.
