--- Comment #1 from Jonathan Larmour <jifl@ecoscentric.com> 2012-03-11 23:22:21 GMT ---
I would like to be very sure that GCC 4.6 is not going to try and optimise away
the read. Can you provide a disassembly of something containing that macro,
compiled with -O2 ? I don't have a suitable GCC 4.6 available to me here.

Thanks,

Jifl
