[LTP] [PATCH V3 1/2] tst_timer: Add support for kernel's 64 bit timespec

[Cyril Hrubis]

Hi!
> include/tst_timer.h is broken on gcc 4, which we have in Travis (CentOS 6).
> I don't know how to fix this, but maybe fix is trivial.
> Or is it time to finally drop this oldest distro? If it's easy to fix, I'd

> still use old compilers).

Looks like there are some problems with the anonymouns unions, probably
gcc 4.4 does not support these. I will have a look later on.
