Tests fsbv.1 and fsbv.2 added that test foreign structure call and
return by value.  This includes the C file and addition to makefile to
generate the appropriate library, libfsbv.  So that the tests are
properly defined, load cffi-fsbv and then cffi-tests.  Both tests
should pass.  The test returning a structure, fsbv.2, exposed an error
in the form generated by ffcall-body-libffi; because it always
generated a mem-aref on the return value, the subsequent
translate-from-foreign was effectively making a double translation.
Thus, this form generation has been conditionalized so that if
translate-from-foreign will not be applied (e.g., built-in-type) to
call mem-aref, otherwise just return the pointer.

As of OSX 10.6.6, loading things like CoreFoundation on something
other than the initial thread results in a crash.

Implemented workaround on SBCL based on what CCL does upstream. Other
Lisps might benefit from similar workarounds.

- Using #-windows instead of #-(or win32 mswindows) which didn't work
  on Clozure CL.

Suggestion and initial patch courtesy of Josh Elsasser.

- Preliminary (likely buggy) version.  Includes documentation and tests.
- New cffi-features: big-endian and little-endian determined with CFFI
  code.
- Needs cleaning up.

- cffi-tests.asd: use gmake on solaris too.
- new cffi-features: sparc[64] and hppa[64], SCL-only.
  (updated the respective test)
- libraries.lisp: handle ERROR instead of SIMPLE-ERROR.
- tests/bindings.lisp: bugfix?

Patch courtesy of Douglas Crosher.

- Make the test-suite run both with and without rt::*compile-tests*
  bound to T.

- Make defcfun.undefined an expected failure for SBCL on
  non linkage-table platforms.
- New file: tests/misc.lisp.
- Added a couple of tests for cffi-features.

- Makefile: new test-scl target. Add SCL's fasl file extensions
  to the clean target.
- Remove SCL TODO item.
- New file: cffi-scl.lisp.
- New primitive type :long-double. Since it's only supported by
  SCL, it's not worth adding a no-long-double feature just yet.
- New tests for :long-double.
- Add information about SCL and the new :long-double type to
  the user manual.

- Updated cffi-ecl.lisp, courtesy of Michael Goffioul.
  (Includes some ECL specific workarounds in the portable
   bits of CFFI.)

- New tests: tests/enums.lisp (4 tests) and tests/misc-types.lisp (3 tests).
- New file: objects.lisp, skeleton of the safe typed pointer interface. I
  also added a :boolean type here, it's looking for a better home still.
- (early-types.lisp): type parsers, DEFINE-TYPE-SPEC-PARSER and PARSE-TYPE.
  Added abbility to have anonymous types (ie. a name is no longer required
  for FOREIGN-TYPE). Moved DEFCTYPE to types.lisp.
- (enum.lisp): improved DEFCENUM, the values for each keyword are now
  optional, like in C. Added the anonymous type (:enum ...)
- (types.lisp):
    - Renamed :TO-C-ARG to :TO-C-DYNAMIC.
    - Renamed FOREIGN-AREF to MEM-AREF and implemented compiler macros
      for it.
    - New exported macro: DEFINE-FOREIGN-TYPE for parameterized types.
    - Change DEFINE-TYPE-TRANSLATOR back to the previous interface,
      translators take a type argument now and we have translators
      available at runtime now too.
    - FOREIGN-TYPEDEF's now inherit their parent type's translators.
    - New :wrapper type, for anonymous typedefs with translators.
- (strings.lisp): Renamed string to :string. Added new type, :string+ptr.
- (utils.lisp): renamed let-if to bif.
- (tests/callbacks.lisp): two tests were not being run for SBCL
  because I thought it triggered a bug but it's actually only one that
  triggers the bug. Fixed that.
- Updated examples and tests to use :string instead of string.

- Move #-cffi/no-foreign-funcall from cffi-tests.asd to
  tests/funcall.lisp and have the lisps that don't support this
  push the feature in cffi-<lisp>.lisp instead of defpackage.
- New file: utils.lisp
- Make Allegro, CMUCL, Corman and OpenMCL use callback-symbol-name  (from cffi-utils) to safely intern callback symbol names (James)
- Clisp: consider (pointerp NIL)

- New interface: DEFCALLBACK, CALLBACK, GET-CALLBACK
- New CALLBACK.* tests.
- Implementations of CFFI-SYS:MAKE-CALLBACK:
    - Allegro, passes all tests on linux/x86 and win32
      fails CALLBACKS.CHAR/UNSIGNED-CHAR/SHORT/UNSIGNED-SHORT
      on darwin/ppc, looks like an Allegro bug.
    - clisp, passes all tests.
    - cmucl, passes all tests on linux/x86, on darwin/ppc fails
      CALLBACKS.CHAR/UNSIGNED-CHAR/SHORT/UNSIGNED-SHORT, looks
      like a bug in cmucl/ppc too.
    - sbcl, x86 only, passes all tests except its callbacks
      can't handle sap's yet, that'd be bug in sbcl too.
    - openmcl, fails CALLBACKS.FLOAT/DOUBLE, I reported this
      bug in openmcl, and it has been confirmed.
    - Lispworks, passes all tests on darwin/ppc, on linux/x86
      and win32 there are issues unrelated to callbacks.

* Push :cffi/no-foreign-funcall to *features* when the host
  lisp does not support it.
* Don't run the funcall tests when #+cffi/no-foreign-funcall
* Unexport foreign-var-ptr, it's meant to be used by defcvar
  only.

Add unit testing framework using RT.
Lots of manual and CFFI-SYS updates.
Add passing a double float to sprintf in examples.lisp.
Update the syntax of the nested structure example.
Add the INC-PTR function to the CFFI-SYS backends.
Add the shareable byte vector interface to the CFFI-SYS backends.
Started writing support for aggregate structure slots.  Not used yet.
