Well I initially took some examples only. Now I extracted allowed values from
GCC development version sources and even built ancient gcc-2.95.3 for Linux ix86
(no x86_64 support available for gcc-2.95.3). The result is that I did not
find any combination when __STDC_VERSION__ is defined and and is less than 199901L
Test script (editing compiler list required) and results are in attachments.
I did the tests under Linux
