C Compiler History
C Compiler
GCC version
The History of GCC
C89/C90 -> C95 -> C99 -> C11 -> C17/C18 -> C2x
Use __GNU_LIBRARY__, __GLIBC__ and __GLIBC_MINOR__ to grab GCC version.

#include <stdio.h>

#include <string.h>
int main(void)

#endif
#ifdef __STRICT_ANSI__
puts("__STRICT_ANSI__");
#endif
return 0;
