Ok, I just committed it to CVS.  I added the feature as "constasvar",
and it works on all constants (including enums).  You can apply it
globally by adding

%feature("constasvar", "1");

or by using -features constasvar on the command line, or applying the
feature to individual constants or enums (see the docs on how to do
that... in CVS, I updated Guile.html with a paragraph about constasvar)


Note, you can test gnucash with the CVS version of SWIG if you just
check SWIG out, run ./autogen.sh && ./configure && make

then, in gnucash just use /path/to/SWIG/CVS/preinst-swig

preinst-swig is a shell script that sets up all the paths and such to
use SWIG directly from the build directory.  And since the generated
wrapper files don't need any part of SWIG installed, once they are
generated they work without needing to know the path or anything.  So,
it would be nice if you tested out the constasvar feature before we make
a release.

As to how many people use guile, I have no idea.  The thing about SWIG
is, there is a large amount of documentation, examples, and all the
examples in the test suite, so I think a lot of people use SWIG without
sending questions to the list or anything.

The data from the survey (http://www.swig.org/survey.html) says 56
people marked Guile during the month of July, versus a total of 2285
survey submissions.  So over 50 downloads a month is pretty big (didn't
check any other months, but I assume they are close).  Remember, many
people may download directly from
http://sourceforge.net/project/showfiles.php?group_id=1645 or use the
package from their distro, so the true number of people using guile will
be larger.

PS: gnucash-devel mailing list kept rejecting my posts, so I will try
again but maybe noone else is seeing this.
