* HAVE_STDBOOL_H is not available when distributed as a library, but no build
* configuration variables may be used (like those above) because the header
* is sometimes only available when using special compiler flags to enable the
* c99 environment. Because we cannot force the usage of this flag, we have to
* provide a default type. Below what is suggested by the autoconf manual.
