Here is my attempt. I added #callconv macro, that accepts a
calling convention parameter. The lines below are now equivalent.

#ccall do_something , CString -> IO CInt

#callconv do_something , ccall , CString -> IO CInt

Would you mind give it some testing (and of course sugestions as
you wish) before I upload it to Hackage? The link below gives
you a few options for download format. Look for version 1.0.5.


There are a few good C libraries that work well under Linux and
Windows (libusb1.0 for Windows is in beta now, for instance). Do
you think we should have a macro that defaults to 'ccall' in Linux
and others and to 'stdcall' on Windows? If so, I would need some
help to avoid portability issues (like a list of platforms and
proper defaults).

Thanks for your toughts,
