It seem these g_assert_nonnull/null functions are in fact just trivial
macros, so we could alternatively add them to our glib-compat.h file



#define g_assert_true(expr)             G_STMT_START { \
                                             if G_LIKELY (expr) ; else \
                                               g_assertion_message (G_LOG_DOMAIN, __FILE__, __LINE__, G_STRFUNC, \
                                                                    "'" #expr "' should be TRUE"); \
                                        } G_STMT_END
#define g_assert_false(expr)            G_STMT_START { \
                                             if G_LIKELY (!(expr)) ; else \
                                               g_assertion_message (G_LOG_DOMAIN, __FILE__, __LINE__, G_STRFUNC, \
                                                                    "'" #expr "' should be FALSE"); \
                                        } G_STMT_END
#define g_assert_null(expr)             G_STMT_START { if G_LIKELY ((expr) == NULL) ; else \
                                               g_assertion_message (G_LOG_DOMAIN, __FILE__, __LINE__, G_STRFUNC, \
                                                                    "'" #expr "' should be NULL"); \
                                        } G_STMT_END
#define g_assert_nonnull(expr)          G_STMT_START { \
                                             if G_LIKELY ((expr) != NULL) ; else \
                                               g_assertion_message (G_LOG_DOMAIN, __FILE__, __LINE__, G_STRFUNC, \
                                                                    "'" #expr "' should not be NULL"); \
