I think the mkdir module in gnulib should depend on the xalloc

Oops.  I checked in the following change.

I don't understand why you should need to do this now that both
-I../libgnu and -I$(top_srcdir)/libgnu appear in the CPPFLAGS
variable.  The gnulib stat.h file should be placed in the libgnu/sys
subdirectory in your build tree and the compiler should find it
there.  You should not have to copy any files by hand to build
Octave.  The configure script and Makefiles should do all the work.
