That's not actually the complete story. :-)
Counters such as these are *carefully* crafted so they can do a 32 bit
subtraction & compariso

We do welcome patches that addresses 64 bit hosts, we just
need to make sure that the basis is right before we hunt down
& modify 100 places :-)

I don't understand. Subtraction is identical for signed and unsigned in
two

What's wrong with this code?
long long then=timeval_ms();

Hi,
The attached patch fixes several warnings when building on an x86_64
system. The changes are trivial.
Most of the issues stem from the fact that:
1) a variable of type long is 8 bytes on x86_64, but is 4 bytes on IA32
2) hex literals with the suffix 'ul' are 8 bytes on x86_64, meaning
severa
