Cast to s64 some variables and a macro in order to give the
compiler complete information about the proper arithmetic to
use. Notice that these elements are used in contexts that
expect express

Yeah, I get your point and it seems that in this particular case there
is no risk of a 32bit overflow, but in gener

Cast to s64 some variables and a macro in order to give the
compiler complete information about the proper arithmetic to
use. Notice that these elements are used in contexts that
expect expressions of type s64 (64 bits, signed).
Currently such expression are being evaluated using 32-bit
arithmetic
