+Subject: [PATCH 1/2] Fixed missed #include <stdlib.h> (see #305)
+
+This code used to compile on everywhere, but explicit #include <stdlib.h>
+was actually missed. Seems that sometimes it can cause problems.

+Subject: [PATCH 2/2] Fixed build with recent versions of libxml2 (fixes #305)
+
+libxml2 recently changed a prototype of the xmlStructuredErrorFunc callback,
+adding const modifier to the second parameter.
+
+Adding an explicit cast seems to fix the problem (but I will not be surprised, if
+this fix will not work equally well on all distros).
+
+Found for a first time and fixed on Arch linux on about 2 Dec 2023 (Arch is rolling
+release, so there is no explicit release number)
