Yes, in practice __STDC_VERSION__ is not reliable in general. Compilers 
define it even when they are not fully conforming, and they don't define 
it even when they support all the standard features one happens to need. 
See, for example, the thread containing this message:

http://lists.gnu.org/archive/html/autoconf-patches/2012-10/msg00006.html

__STDC_VERSION__ can be used in some cases, but I don't think this is 
one of the cases. So I removed the check.
