I think you'll find when you do this:
$ pkg-config sigc++-2.0 --cflag
They have done this against our wishes:
https://bugzilla.gnome.org/show_bug.cgi?id=755750#c13
This is very much a distro-specific problem that you should complain to
your distro about. Sorry. I am annoyed with them, not with you. Thanks
for letting me know.
