Continuing my build from i386 to VAX on the same sources as before, it
now fails in X sources:

includes ===> x11/lib/Xpm
    install  /vol1/rhialto/destdir.vax/usr/X11R6/include/X11/xpm.h
includes ===> x11/lib/Xt
    compile  makestrs/makestrs.lo
/vol1/rhialto/cvs/xsrc/xfree/xc/config/util/makestrs.c:33:21: error: X11/Xos.h: No such file or directory
...more errors...
*** Failed target:  makestrs.lo
*** Failed command: cc -O -I. -c -o makestrs.lo.o /vol1/rhialto/cvs/xsrc/xfree/xc/config/util/makestrs.c
*** Error code 1

Stop.

but destdir.vax/usr/X11R6/include/X11/Xos.h is there..
It seems like a -I option is missing somehow. Other cross builds (amd64
to Alpha and i386) worked fine.

-Olaf.
