KWIML defines format string macros matching the fixed-sized types. This
test checks that they behave as expected and that the arguments match
the *sizes* expected by the format strings.
Provides header files that use preprocessor tests to detect and provide
information about the compiler and its target architecture. The headers
contain no configuration-time test results and thus may be installed
into an architecture-independent include directory. This makes them
suitable for use in the public interface of any package.
