How can i check by a preprocessor directive if the type unsigned long long
is available in the current build environment?
I tried checking
#if __STDC_VERSION__ >= 199901L
/* Available */
#else
/* Not available */
#endif
but compiling with gcc and at least without -std=
-compiler argument this leads to "Not avaibalble" (but would work).
Is there a better macro to check so that at least it works with C99 standard compilers and with GCC without -std=C99
?
