I tested this also before committing. I could not find a problem.
I only have an x86_64 machine on redhat linux and a raspberry pi with 32 
and 64 bits.
I also have no Windows any more and my i386 machine died about 10 years ago.
So I did the measurement with wine (32/64 bits) and saw no difference 
before and after commit.

I did make a small change to the hash function. See attached patch.
(I used a 32 bits hash instead of 64 bits)

I cannot currently think of a better solution for pragma once. Maybe you 
can?
