Suppleness of the sheaf of algebras of generalized functions on manifolds

We show that the sheaves of algebras of generalized functions $\Omega\to $\mathcal{G}$(\Omega)$and$\Omega\to $\mathcal{G}$^{\infty}(\Omega)$,$\Omega$ are open sets in a manifold $X$, are supple, contrary to the non-suppleness of the sheaf of distributions.
