Re: [f2py] f2py: error: unknown file type '' (from '--include_paths')

Hi Pearu,

Thanks for the fix. I found a work-around that works well for me: just
run f2py twice. 

The first run is to generate a signature file, using --include_paths
option with colon-separated list of include dirs.
The second run actually compiles the stuff, using multiple -I options
(one for each include dir).

What still puzzles me is how I should steer the choice of compiler, but
since that's a different topic, I'll start a new thread for that.

Best regards,
Marcel Loose.
