sleep_for is not always defined with gcc <= 4.7, see
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=52680
To fix this issue, add -D_GLIBCXX_USE_NANOSLEEP if gcc version is lower
than 4.8

First comment in the bug report says:
"""
Don't define that manually, you should configure gcc with
--enable-libstdccxx-time instead.
"""
So I'm not sure enthusiastic with going in this direction. What about
making domoticz depend on gcc >= 4.8 ?
Best regards,
Thomas
