In C99 __STDC_VERSION__ is defined as 199901L. Thus, something like
this should work:
#ifdef __STDC_VERSION__
#if (__STDC_VERSION__ == 199901L)
/* okay */
#else
/* __STDC_VERSION__ is defined but not 199901L */
#error This compiler is not C99-compliant!
#endif
#else
/* __STDC_VERSION__ is not defined */
#error This compiler is not C99-compliant!
#endif
You can read more about that in the C99 standard, ANSI/ISO/IEC
9899-1999 in paragraph 6.10.8.
