[Haskell-cafe] video for linux two (v4l2) bindings

[Maurício Antunes]

Hi, all,

I've added that 'extra-libraries' to .cabal, and also modules for fcntl.h
and sys/mman.h (mmap). Would you please test it and check if it solves
the problem before I upload it to hackage?

  https://bitbucket.org/mauricio/bindings-dsl/downloads/bindings-posix-1.2.3.tar.gz

Just download from that link, unpack and do 'cabal install' inside the
new directory.

Best,
Maurício
