[avr-gcc-list] __STDC_VERSION__ not defined

[Victor Aprea]

Hey all,

I'm working on porting a library and I've run across an unfortunate surprise (or I'm just doing it wrong). 

Can someone confirm that avr-gcc 4.8.1 doesn't (implicitly) define __STDC_VERSION__ as suggested by https://gcc.gnu.org/onlinedocs/cpp/Standard-Predefined-Macros.html#Standard-Predefined-Macros? If not, how is a library to determine if the compiler is C89 or C99 or whatever?

Kind Regards,
Vic
