Abstract types now have names.
Pretty-printing of object and function types.
Findlib target for installing top-level pretty printers for types.
Correct section header.
Consistently use 'type a. ...' syntax for signatures.
Printers for signed and unsigned integer types.
Printing for pointers.

  # let getenv = Foreign.foreign "getenv" (string @-> returning (ptr char));;
  val getenv : string -> char Ctypes.ptr = <fun>
  # getenv "USER";;
  - : char Ctypes.ptr = (char*) 0x7ffff65bfa7b
  # getenv "A";;
  - : char Ctypes.ptr = (char*) (nil)
General printing for C values.
Top-level printers for POSIX types.

  # let time = Foreign.foreign "time" (ptr void @-> returning time_t);;
  val time : unit Ctypes.ptr -> PosixTypes.time_t = <fun>
  # time null;;
  - : PosixTypes.time_t = 1372340341
Print floats and doubles with more precision.

Generic printing for C types and values
Treat sealing empty structs or unions as an error.
Merge pull request #28 from yallop/empty-structs-and-unions

Treat sealing empty structs or unions as an error.
Record passability for primitive types.
Add string_opt view

Sometimes a "char *" isn't actually a string, but nothing at all.
Merge pull request #31 from robhoes/master

Add string_opt view
Support for C99's complex number types.

Complex numbers are not currently passable, since libffi doesn't
support the complex types.

The names complex32 and complex64 come from the Bigarray module; we
may want to revisit that choice.
Treat sealing empty structs or unions as an error.
Add the 'camlint' basic type.

Values of camlint appear as OCaml ints and have the same storage requirements
as value.  The main (and perhaps only) use is for exposing Bigarray.int_elt.
