-/* ================================================================ */

-/*
- * NOTE 1:
- * -------
- *
- * All checks done in this file are intentionally placed in a public
- * header file which is pulled by ares.h when an application is
- * being built using an already built c-ares library. Additionally
- * this file is also included and used when building the library.
- *
- * If compilation fails on this file it is certainly sure that the
- * problem is elsewhere. It could be a problem in the ares_build.h
- * header file, or simply that you are using different compilation
- * settings than those used to build the library.
- *
- * Nothing in this file is intended to be modified or adjusted by the
- * c-ares library user nor by the c-ares library builder.
- *
- * Do not deactivate any check, these are done to make sure that the
- * library is properly built and used.
- *
- * You can find further help on the c-ares development mailing list:
- * http://cool.haxx.se/mailman/listinfo/c-ares/
- *
- * NOTE 2
- * ------
- *
- * Some of the following compile time checks are based on the fact
- * that the dimension of a constant array can not be a negative one.
- * In this way if the compile time verification fails, the compilation
- * will fail issuing an error. The error description wording is compiler
- * dependent but it will be quite similar to one of the following:
- *
- *   "negative subscript or subscript is too large"
- *   "array must have at least one element"
- *   "-1 is an illegal array size"
- *   "size of array is negative"
- *
- * If you are building an application which tries to use an already
- * built c-ares library and you are getting this kind of errors on
- * this file, it is a clear indication that there is a mismatch between
- * how the library was built and how you are trying to use it for your
- * application. Your already compiled or binary library provider is the
- * only one who can give you the details you need to properly use it.
