I think you're referring to the "-L/usr/X11R6/lib" in X_LIBS and the fact
that -lICE and -lSM are in that directory?
I think thats not a problem, because I think the order of the "-L" with 
respect to the "-l" options doesn't matter.  The "-L" just globally modifies 
the search path to use to find libs.  Yes/No?

Otherwise AC_PATH_XTRA would seem (even more) broken.
