+Subject: [PATCH] array: Don't use realloc() with zero size in array_compress()
+
+The behavior of realloc(3) with zero size was apparently implementation
+defined.  While glibc documents the behavior as equivalent to free(3),
+that might not apply to other C libraries.  With C17, this behavior has
+been deprecated, and with C23, the behavior is now undefined.  It's also
+why valgrind warns about this use.
+
+Hence, when array_compress() would call realloc() with a zero size, we
+now call free() explicitly and set the pointer to NULL.

+Subject: [PATCH] callback-job: Replace return_false() in constructors with
+ dedicated function
+
+Besides being clearer, this fixes issues with GCC 15.  The latter uses
+C23 by default, which changes the meaning of function declarations
+without parameters such as
+
+	bool return false();
+
+Instead of "this function takes an unknown number of arguments", this
+now equals (void), that is, "this function takes no arguments".  So we
+run into incompatible pointer type warnings all over when using such
+functions.  They could be cast to (void*) but this seems the cleaner
+solution for this use case.

+Subject: [PATCH] Cast uses of return_*(), nop() and enumerator_create_empty()
+
+As described in the previous commit, GCC 15 uses C23 by default and that
+changes the meaning of such argument-less function declarations.  So
+whenever we assign such a function to a pointer that expects a function
+with arguments it causes an incompatible pointer type warning.  We
+could define dedicated functions/callbacks whenever necessary, but this
+seems like the simpler approach for now (especially since most uses of
+these functions have already been cast).
