Try to fix a 64-bit powerpc g++ 7 warning

Browse Source 
Warning is:

allocate.hpp:335:19: warning: conversion to ???unsigned int??? from
???long unsigned int??? may alter its value [-Wconversion]

I'm not sure, but I think it's because the sizeof is a long unsigned
int, and the template parameter is an unsigned int. The sizeof isn't
even used, it's just there to get a value for expression SFINAE.
