/*                    COMPILE TIME SANITY CHECKS                    */

/* ================================================================ */

/*

 * NOTE 1:

 * -------

 *

 * All checks done in this file are intentionally placed in a public

 * header file which is pulled by curl/curl.h when an application is

 * being built using an already built libcurl 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 curlbuild.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

 * curl library user nor by the curl 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 libcurl development mailing list:

 * http://cool.haxx.se/mailman/listinfo/curl-library/

 *

 * 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 libcurl 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.
