Odd; my config.log has:

	configure:4675: warning: implicit declaration of function `XtMalloc'

which implies that it isn't picking up the header. In fact, the
relevant portion of the configure script is:

	cat > conftest.$ac_ext <<EOF
	#line 4672 "configure"
	#include "confdefs.h"
	
	int main() {
	${x_direct_test_function}()
	; return 0; }
	EOF

which doesn't include any X headers.

Have you re-built your configure script using a different version of
autoconf?
