Good. Therefore let's just start with 2 longs as bitmap, everywhere, and 
we are
done once and for all!

Yes, of course, but see above. Also, please document that 8 in struct 
_Alloc_block:
it must be very clear that raising to 16 guarantees alignment 16.

Basically, the patch, besides the 2 above, boils down to a search and 
replace
s/int/long/, right? No need of additional weird computations and casts!
