Can the design be altered so that config.status replaces itself by
running a temporary script while config.status is replaced?  The key
would be to avoid a sharing violation under Windows or operating
systems that prevent an executing script from being replaced.

Yes.  For the project I maintain, I typically have some 20 build
directories sharing a common source directory and when I make a
configure-related update it would be nice if 'config.status --recheck'
would be sufficient so I wouldn't have to recollect the options used
to build that directory.

On a related topic, the message printed by 'config.status --recheck'
is incorrect.  The message printed is not properly quoted.  For
example:

% ./config.status --recheck
running /bin/bash /home/bfriesen/src/graphics/ImageMagick/configure
CFLAGS=-O2 -g CXXFLAGS=-O -g --enable-maintainer-mode
--with-quantum-depth=8 --enable-lzw --enable-shared --disable-static
--with-windows-font-dir=/usr/local/lib/X11/fonts CC=gcc
--enable-ltdl-convenience  --no-create --no-recursion

Does not show the quoting of the CFLAGS and CXXFLAGS options required
to reflect what is actually being executed.
