When checking a function in the xerces-c library,
needed to link with -lpthread.

In addition any files linked with -lxerces-c needed
-lpthread in the configure script:

XERCES_VERSION=2.3.0
AC_CHECK_HEADERS([xercesc/util/XercesVersion.hpp],[AC_DEFINE([SUPPORT_X3D],1,[X3D])],[AC_MSG_RESULT(no)])
AC_CHECK_LIB(xerces-c,main,[[LIBS='-lxerces-c
-lpthread']],[HAVE_LIBXERCESC=0],[ -lpthread])
