To fix it, I tweaked the configure script again.
The patch attached introduce "release mode" for configure generation.
With this patch, configure script generated by "autogen.sh --release"
does not have --with-swig|--without-swig option and never check SWIG
executable.
Could anyone please review this?
For backward compatibility to back port to 1.14.x, default for
--with-swig-perl, --with-swig-python, --with-swig-ruby are "auto",
i.e. search the target language, but I'd like to change them to "no" in
trunk, because I think those are optional feature.
Thanks,

Distinguish configure scripts on release mode and non release mode.
Although makefiles in the Subversion's release tarball do not support to
genarate SWIG language bindings C source files using swig, the configure
scripts shipped with release tarball had a option to specify how to find
SWIG executable, and checked it. To avoid this, we introduce "release mode"
to the configure script and hiding an option and code to check a SWIG
executable on it.
* . (svn:ignore):
Ignore aclocal.m4.
* aclocal.m4 ():
Renamed to aclocal.m4.in
* aclocal.m4.in ():
Renamed from aclocal.m4.in
* autogen.sh ():
Define SVN_RELEASE_MODE macro if --release is specfied from command line.
* build/ac-macros/swig.m4
(): Also mension about Perl and Ruby.
(SVN_CHECK_SWIG):
- Hide --with-swig option in release mode.
- Check SWIG executable only if non release mode and at least one of
SWIG bindings is specfied to be built.
(SVN_FIND_SWIG):
Move checks for each bindings into new macro SVN_DETERMINE_SWIG_OPTS.
(SVN_DETERMINE_SWIG_OPTS): New macro. Devided from SVN_FIND_SWIG.
- On non releasemode, warn if Perl/Python/Ruby interpreter is set but
SWIG is not found. Also it prevent build them on make swig-pl/make
swig-py/make swig-rb in such case.
- Check swig version only on non release mode and it is needed
* configure.ac ():
- Tweak help string for --with-swig-perl, --with-swig-python,
--with-swig-ruby.
- Warn if --with-swig-perl is not specified but variable 'PERL' is set.
- Warn if --with-swig-ruby is not specified but variable 'Ruby' is set,
even the value is not 'no' nor 'none'.
* subversion/bindings/swig/INSTALL (Step 2):
Mension that configure and makefiles in release tarball don't
support generation of SWIG bindings C source files.
