If you "commmit" what you have, others can look at it.

Remember ...  "WIP" branches are workspaces, not necessarily 
working.  It is quite reasonable to "commit" non-working code 
and asking for help.

The non-WIP non-master branches are really also work in 
progress, but are mature enough to say "it works for me!  I 
think it is good.  What do you think?"

Regarding this particular warning ...  One possibility is that 
the glibmm code quality isn't as good as it should be.

More likely, there is a mismatch in how you called some library 
function that eventually calls that one inside.  This is one of 
the ugly parts of the C++ header system.

Often you will see a long chain of "included from here" 
connecting that to where you called it.  Trace it back to your 
code.  Most likely there is a type mismatch there.
