You're right.

As I prefer not to recompile gtkmm (windows is not my primary target,
and I did not succeed to compile it simply running msvc on the .sln), I
choose another hack :

https://github.com/BastienDurel/NR-deckbuilder/commit/16457166a8ae92ce9828fc9b4d0f007f3ab893c6

this will not solve already-compiled code, but is sufficient to use
compose.

Thanks for looking.
