Fixed in my last cvs commit.  It is impressive that we have never included a
MY_ARG_WITH for the --with-double option.

I do not see a problem with this.  I usually do "./configure --help | less".
What we have absolutely to do is to update and improve the documentation in
doc/docbook/src/os_notes.xml.

I do not know exactly what you mean.  If you are suggesting that configure
should accept new sub-help options like --help-foo and --help-bar, I think
we are out of hope.  If you are talking about a better presentation when
./configure --help is run, we could do something.

For instance, if I modify the MY_ARG_WITH(double,...) that I just committed
to read:

MY_ARG_WITH(double,[
Options that will affect the behavior of the library:
]AC_HELP_STRING([--with-double],
    [Compile the library with double precision floating point
     ($with_double)]))
 
then I have:

./configure --help
[...]
  --with-mkoctfile=file   Specify mkoctfile
  --with-octavex=file      Specify Octave

Options that will affect the behavior of the library:
  --with-double           Compile the library with double precision floating
                          point ($with_double)
  --with-www-user=NAME    User name at WWW host
[...]

Of course, this will only be meaninful if we do a reorganisation of
configure.ac and sysloc.in to regroup the calls to MY_ARG_WITH and
MY_ARG_ENABLE in a logical order.
