From 0ad948ede2b5060a144c72e4e27c38d24a272ef4 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Define LIBXML_THREAD_ALLOC_ENABLED via xmlversion.h

Otherwise, direct calls to xmlFree() etc. from the application will
use a different set of allocation functions to what was used to allocate
the memory internally.
