[Libguestfs] [PATCH nbdkit 2/2] common/include/checked-overflow.h: Provide fallback

[Richard W.M. Jones]

(Catching up ...)

The maths looked reasonable.  Did you have a version of the patch for
review?

My only other thought is that a simple set of tests could be good.
However it's not worth having tests that only test if __builtin*
functions are correct (hopefully GCC is already testing that).  So
tests would have to check the fallback macros are correct, even if
they are not used on the current platform.

Rich.
