Hi Aleksey,

Thanks for the quick response.

Good news! I didn't see this in the changelog. Is it documented  
anywhere? As I mentioned, I use GODI for installing most OCaml  
software. The Menhir package that comes with GODI has examples under  
godi/share/doc/menhir/demos. The OMake commands they define take an  
extra "flags" argument (i.e., MenhirMulti(target,sources,flags)). I  
think this is easier than using the global MENHIR_FLAGS variable,  
namely because of the --tokens-only and --external-tokens flags.  
Would it be possible to add this capability to OCaml.om?

Alas, I am an OS X user. I have been hoping that this was going to be  
fixed. I'll be looking forward to 0.9.8.2 :)
