I am testing rebuild of SWIG dependencies against upcoming version 4.1.0 in Fedora rawhide/38.

The test of openwsman-2.7.1 is failing with this version.

/builddir/build/BUILD/openwsman-2.7.1/build/bindings/ruby/openwsman_wrap.c: At top level:
/builddir/build/BUILD/openwsman-2.7.1/build/bindings/ruby/openwsman_wrap.c:3906:19: error: static declaration of 'SwigClassXmlDoc' follows non-static declaration

It is caused because SWIGVERSION macro is no longer defined.
The macro is used in bindings/ruby/helpers.h.

Upstream already fixed it.
