But surely this should not be necessary when building from a tarball? All the
HTML should be in the tarball already.

Indeed.  Then there must be something wrong with gtkmm-documentation 2.14.0,
which builds the tutorial anyway though htmls are already generated, and I
haven't figured out why yet.

gstreamermm does not use compiler warning flags, and while debugging a crash in
some code I was working on, enabling warnings allowed me to find the problem
and fix it.

There is an apparently-unused "GSTREAMERMM_ARG_ENABLE_WARNINGS" in configure.ac
that caught my eye.

Add compiler warnings to build system

This patch adds support for warning flags to the build system, using Daniel

I came across an issue in gstreamermm that caused my code to crash. The code in
question utilises the parse() member function of Gst::MessageStateChanged. In
gstreamermm, the parse() function dereferences an unitialised pointer. On
closer inspection, parse_old() and parse_pending() were also affected, and all
three functions were also unnecessarily using NULL and casting to State
incorrectly.

Well done. I would add some more initialize in place such as this, in case
gstreamer doesn't do it always:

GstState pending_state; //Choose an arbitary initial enum value - maybe
GST_STATE_NULL.
gst_message_parse_state_changed(const_cast<GstMessage*>(gobj()), 0,
