You have compiled the R4 Xt library with R3 Xt include files.  Check all
the -I options on the cc lines; one of them (or the final implicit
-I/usr/include) will point to a directory inside which the X directory has
stale .h files.

If it hadn't said "recompilation needed", it would have meant you are
mixing R4 widgets with an R3 Xt.
