Seems pretty brute-force. Why not just

#if LIBXML_VERSION > 20703
#define HAVE_XMLSTRUCTUREDERRORCONTEXT
#endif

in some suitable place (probably xml.c itself, since I don't think we
want to #include xmlversion.h in global headers)?

Or actually, maybe we could just unconditionally define
HAVE_XMLSTRUCTUREDERRORCONTEXT in pg_config.h.win32. Is anybody
likely to still be building PG with ancient libxml on Windows?
