Maybe something like:

%define bcond_with()	%{expand:%%{?_with_%{1}:%%define %{1} 1}}
%define bcond_without()	%{expand:%%{!?_without_%{1}:%%define %{1} 1}}

And then:

%bcond_with	foo	# foo inc. support
%bcond_without	bar	# bar fonts support

%ifdef foo
...
%endif

%ifdef bar
...
%endif

%{?foo: ... }
%{?bar: ... }

Would be nice?

But it doesn't seem to work...
