Workaround for including stdint.h on older GCC versions

Browse Source 
GCC doesn't set __STDC_VERSION__ for older versions. It is verified to
be set by default on 5.3.0.

Older versions set __INT64_MAX__ though (oldest version tested is
4.5.4).

If compilation with older GCC versions is required, set -std=c99. Even
3.4.6 is supported with this setting.
