Description

Is your feature request related to a problem? Please describe. GHCJS cannot compile accelerate.

Describe the solution you'd like GHCJS to successfully compile accelerate.

Describe alternatives you've considered Don't use accelerate.

Additional context accelerate currently uses foreign C calls that fail under GHCJS. Additionally, the terminal-size dependency does not compile with GHCJS.

I'm not sure how practical it would be to support compilation under GHCJS, but it would make accelerate an even more backend agnostic framework for computation. With GHCJS, accelerate could run on the web, in addition to CPUs and GPUs.

Research direction
First, identify the specific foreign C calls in the accelerate source that fail under GHCJS by reviewing the error logs or attempting a build. Then, investigate the terminal size dependency to see if an alternative exists or if it can be made GHCJS compatible. Finally, assess the overall feasibility and scope of changes needed to support GHCJS, considering the use of FFI and cabal flags.
