You can probably see an example of the #warning preprocessor in all standards in the include /usr/include/features.h:
#warning
/usr/include/features.h
// ... #if (defined _BSD_SOURCE || defined _SVID_SOURCE) \ && !defined _DEFAULT_SOURCE # warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE" # undef _DEFAULT_SOURCE # define _DEFAULT_SOURCE 1 #endif // ...
