Details:

I've pulled the latest code, run ./bootstrap, run make (for which configure is
re-run), and when reaching the point of documentation compiling notice the
following error:


  GEN      build-aux/mk-default-qt-settings.sh
config.status: creating build-aux/mk-default-qt-settings.sh-tmp
config.status: executing build-aux/mk-default-qt-settings.sh commands
  GEN      doc/interpreter/doc-cache
refusing to overwrite test/.gdbinit with newer version from
/home/sebald/octave/octave/octave/etc/gdbinit
refusing to overwrite .gdbinit with newer version from
/home/sebald/octave/octave/octave/etc/gdbinit
  GEN      doc/interpreter/voronoi.eps


It seems that the reason for this error is that Makefile has a bad script
within:


define gdbinit_install_rule
  if [ -f $@ ]; then \
    echo "refusing to overwrite $@ with newer version from $<" 1>&2; \
  else \
    echo "Installing $@ from version at $<" ; \
    cp $< $@; \
  fi
endef


My guess is that the conditional should have something like "[ rm -f $@ ]" as
opposed to just "[ -f $@ ]", which always fails.

Although, that may not quite be it, as I manually make the change from the
build directory Makefile and still see a complaint, but success:


  GEN      build-aux/mk-default-qt-settings.sh
config.status: creating build-aux/mk-default-qt-settings.sh-tmp
config.status: executing build-aux/mk-default-qt-settings.sh commands
/bin/bash: line 0: [: -f: binary operator expected
Installing test/.gdbinit from version at
/home/sebald/octave/octave/octave/etc/gdbinit
/bin/bash: line 0: [: -f: binary operator expected
Installing .gdbinit from version at
/home/sebald/octave/octave/octave/etc/gdbinit
  GEN      doc/interpreter/voronoi.eps


Any idea if this might be related to compilation being stuck at the last line
shown?  I.e., after "  GEN      doc/interpreter/voronoi.eps" the compilation
whirls away at max CPU for the better part of an hour until I hit Cntl-C three
times.
