2.6.8: * Fix the build when using --enable-api-properties, --enable-api-vfuncs, or --enable-api-exceptions when configuring glibmm. When using these, the API, and any API generated by gmmproc, will be changed. This allows users of embedded platforms to reduce the code size of *mm libraries and *mm-using applications, at the small cost of losing some rarely-used API. Alternatives exist for that API, as show in the examples.
