Mmmm... I was looking at new warnings, specifically those at t0012
test. At first sight I changed %d to %ld but after a bit (luckyly) I
realized that abi was changed so I checked in vendor headers and I
realize they use long only if sizeof(long) == 4 (that is they use int
if long is.. too long :) ). I think we should rollback or follow
vendor way (always 32 bit).
