26/* COMPILE TIME SANITY CHECKS */
27/* ================================================================ */

29/*
30 * NOTE 1:
31 * -------
32 *
33 * All checks done in this file are intentionally placed in a public
34 * header file which is pulled by curl/curl.h when an application is
35 * being built using an already built libcurl library. Additionally
36 * this file is also included and used when building the library.
37 *
38 * If compilation fails on this file it is certainly sure that the
39 * problem is elsewhere. It could be a problem in the curlbuild.h
40 * header file, or simply that you are using different compilation
41 * settings than those used to build the library.
42 *
43 * Nothing in this file is intended to be modified or adjusted by the
44 * curl library user nor by the curl library builder.
45 *
46 * Do not deactivate any check, these are done to make sure that the
47 * library is properly built and used.
48 *
49 * You can find further help on the libcurl development mailing list:
50 * https://cool.haxx.se/mailman/listinfo/curl-library/
51 *
52 * NOTE 2
53 * ------
54 *
55 * Some of the following compile time checks are based on the fact
56 * that the dimension of a constant array can not be a negative one.
57 * In this way if the compile time verification fails, the compilation
58 * will fail issuing an error. The error description wording is compiler
59 * dependent but it will be quite similar to one of the following:
60 *
61 * "negative subscript or subscript is too large"
62 * "array must have at least one element"
63 * "-1 is an illegal array size"
64 * "size of array is negative"
65 *
66 * If you are building an application which tries to use an already
67 * built libcurl library and you are getting this kind of errors on
68 * this file, it is a clear indication that there is a mismatch between
69 * how the library was built and how you are trying to use it for your
70 * application. Your already compiled or binary library provider is the
71 * only one who can give you the details you need to properly use it.

74/*
75 * Verify that some macros are actually defined.
