+Subject: [PATCH] ext/xml/expat_compat.h: add missing php.h include
+
+When expat support is disabled and libxml support is enabled, the
+following part of the code in expat_compat.h gets used:
+
+and therefore "php".h" is included. However, when libexpat support is
+enabled, HAVE_LIBEXPAT is defined, and therefore the following part of
+the code is used:
+
+In this case, "php.h" is not included. Due to this, zend_alloc.h is
+never included when building the ext/xmlrpc/libxmlrpc/xml_element.c
+file, and therefore the estrdup -> _estrdup macros are never defined,
+causing the following link time failure:
+
+ext/xmlrpc/libxmlrpc/xml_element.o: In function `xml_element_serialize':

+This link time failure can be produced with:
+
+./configure --prefix=/usr --with-libdir=/usr/lib64 --disable-all \
+	    --without-pear --with-config-file-path=/etc --disable-phpdbg \
+	    --disable-cli --enable-cgi --disable-fpm --enable-xmlreader \
+	    --enable-xmlwriter --enable-libxml --enable-wddx --with-xmlrpc \
+	    --with-libexpat-dir=/
+
+We fix it by including "php.h" in the HAVE_LIBEXPAT case.
