Stephan Bergmann 6171812c55 HAVE_GCC_ATTRIBUTE_WARN_UNUSED should always be true now for Clang/GCC
...but for safety, leave the configure.ac check in for some longer.

README

These are configuration files for various features as detected by configure.

Include only those files you need (in order to reduce rebuilds when a setting changes).

Settings here are only C/C++ #define directives, so they apply only to C/C++ source,
not to Makefiles.



Adding a new setting:
=====================

- do AC_DEFINE(HAVE_FOO) in configure.ac when a setting should be set
- choose the proper config_host/config_XXX.h file to use
    - if it is a global setting (such as availability of a compiler feature),
        use config_host/config_global.h
    - otherwise check if there is a matching config_host/config_XXX.h file
    - if none matches, add a new one:
        - add config_host/config_XXX.h.in here, with just #ifndef include guard
        - add AC_CONFIG_HEADERS([config_host/config_XXX.h]) next to the others
            in configure.ac
- add #define HAVE_FOO 0 to the config_host/config_XXX.h , possibly with a comment
  (do not use #undef HAVE_FOO, unless the setting has more values than on/off)
- add #include <config_XXX.h> before any #if HAVE_FOO in a source file
- make sure you use #if HAVE_FOO for on/off settings, do not use #ifdef
