This looks like a new gcc "feature".  From the man page of gcc on my
machine:

        -MM Like -M but do not mention header files that are found in 
system
            header directories, nor header files that are included, 
directly or
            indirectly, from such a header.

            This implies that the choice of angle brackets or double 
quotes in
            an #include directive does not in itself determine whether 
that
            header will appear in -MM dependency output.  This is a 
slight
            change in semantics from GCC versions 3.0 and earlier.

So it doesn't think that /usr/X11R6/include is a system header
directory; I guess we should use the "-isystem" option instead of "-I",
but that would make it even harder to compile OCaml without gcc.
