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)
