/**
 * The boolean type _Bool is C99 while we mostly stick to C89. However, _Bool is too
 * convinient to miss and is effectively available in gcc and clang. So, just use it.
 *
 * Usually, one would include "stdbool.h" to get the "bool" define which aliases
 * _Bool. We provide this define here, because we want to make use of it anywhere.
 * (also, stdbool.h is again C99).
 *
 * Using _Bool has advantages over gboolean:
 *
 * - commonly _Bool is one byte large, instead of gboolean's 4 bytes (because gboolean
 *   is a typedef for gint). Especially when having boolean fields in a struct, we can
 *   thereby easily save some space.
 *
 * - _Bool type guarantees that two "true" expressions compare equal. E.g. the follwing
 *   will not work:
 *        gboolean v1 = 1;
 *        gboolean v2 = 2;
 *        g_assert_cmpint (v1, ==, v2); // will fail
 *   For that, we often to use !! to coerce gboolean values to 0 or 1:
 *        g_assert_cmpint (!!v2, ==, TRUE);
 *   With _Bool type, this will be handled properly by the compiler.
 *
 * - For structs, we might want to safe even more space and use bitfields:
 *       struct s1 {
 *           gboolean v1:1;
 *       };
 *   But the problem here is that gboolean is signed, so that
 *   v1 will be either 0 or -1 (not 1, TRUE). Thus, the following
 *   fails:
 *      struct s1 s = { .v1 = TRUE, };
 *      g_assert_cmpint (s1.v1, ==, TRUE);
 *   It will however work just fine with bool/_Bool while retaining the
 *   notion of having a boolean value.
 *
 * Also, add the defines for "true" and "false". Those are nicely highlighted by the editor
 * as special types, contrary to glib's "TRUE"/"FALSE".
