I checked in the following changeset:

  http://hg.savannah.gnu.org/hgweb/octave/rev/a2ee71d42a06

I'm working on eliminating as many configuration preprocessor symbols as 
possible from public header files and making some header files "private" 
(not installed) so that we can stop installing Octave's config.h.  If it 
turns out to be impossible to avoid some configuration macro from a 
public header file, then that symbol will be moved to a separate 
octave-config.h file that contains symbols that are specific to Octave, 
not general things like HAVE_ACOSH.

While I'm making these changes, I'm sure to break a few things.  If that 
happens, it probably means that it worked for me, but I'm not testing on 
every possible platform.  So please go ahead and report build problems 
on the bug tracker and I'll try to be quick to fix any problems that are 
reported.
