Note that the abs(long) and abs(long long) overloads, which you probably want
around, are actually declared in <cstdlib>, which you are not including
(-std=c++11 of course). Otherwise, <cstdlib>, which is available only because
is included as an implementation detail, is fine per the Standard, any integer
is supposed to unconditionally become double.

But indeed you are right that long term you want <cstdint> to be non empty for
SH. That shouldn't be too hard to implement, there is already very solid
infrastructure for that (as an header installed by GCC, I mean). This is a
target issue, really.
