- * NOTE 1:
- * -------
- *
- * Nothing in this file is intended to be modified or adjusted by the

- *
- * If you think that something actually needs to be changed, adjusted
- * or fixed in this file, then, report it on the c-ares development
- * mailing list: http://cool.haxx.se/mailman/listinfo/c-ares/
- *
- * Try to keep one section per platform, compiler and architecture,
- * otherwise, if an existing section is reused for a different one and
- * later on the original is adjusted, probably the piggybacking one can
- * be adversely changed.
- *
- * In order to differentiate between platforms/compilers/architectures

- *
- * This header file shall only export symbols which are 'cares' or 'CARES'

- *
- * NOTE 2:
- * -------
- *
- * Right now you might be staring at file ares_build.h.dist or ares_build.h,
- * this is due to the following reason: file ares_build.h.dist is renamed
- * to ares_build.h when the c-ares source code distribution archive file is
- * created.
- *
- * File ares_build.h.dist is not included in the distribution archive.
- * File ares_build.h is not present in the CVS tree.
- *
- * The distributed ares_build.h file is only intended to be used on systems
- * which can not run the also distributed configure script.
- *
- * On systems capable of running the configure script, the configure process
- * will overwrite the distributed ares_build.h file with one that is suitable
- * and specific to the library being configured and built, which is generated
- * from the ares_build.h.in template file.
- *
- * If you check out from CVS on a non-configure platform, you must run the
- * appropriate buildconf* script to set up ares_build.h and other local files.

-/* COMPILE TIME SANITY CHECKS */
-/* ================================================================ */
-
-/*
- * 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.
