1. d4 f5 2. h3 Nf6 3. g4 d5 and B is ok. IMHO, the only justification for playing h3 is hoping for 3... fxg4 4. hxg4 Nxg4 5. Qd3 (some players answer Qd3 with Nf6 then Rxh7 +-).
1. d4 f5 2. g4 fxg4 is not much better. If 3. h3 then 3...g3 =

Sometimes White decides to play g4 with the intention of deflecting the f-pawn's influence on the center so that e2-e4 can be played. Quite a few sources, i.e. Beim, now quote the following game for a possible black setup, which suits me since I am playing the French as well.

Certainly not a perfect game, but it goes give you some ideas on how to handle this variation.
If you decide not to accept the pawn with 2. ... fg4 and decide to play 2. ...d5 instead, you might want to have a look at the following game, which is also often quoted in a number of books about the Dutch.

In summary you have two options, don't take the pawn and play d5, or take the pawn and return it with g3 as a response to h3 keeping lines closed.
