Description:
------------
Originally reported by Thomas Petazzoni via <https://github.com/php/php-src/pull/3212>:

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:
