185	non-free properties in usage requirements don't work, generally	grafikrobot@…	somebody	"One effect of non-free props not ""working"" is that adding them to a usage requirement, and a counterpart to a variant, merges the flags for both settings into the build commands. Two options possible to fix it:

  * Make it work, somehow :-)
  * Or, generate a warning (or error) when one has non-free props in usage requirements."	defect	new	minor		component1
