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.

Testing error situations for some pointer operations.

- 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?

Three new features:
  - stdcall (defcfun, foreign-funcall(-pointer), defcallback)
  - namespaces, associate foreigns vars and functions to a
    specific library. (CLISP and Lispworks only)
  - close-foreign-library actually works now.

Backwards incompatible changes:
  - define-foreign-library's syntax changed slightly, can't
    load more than one foreign library per define-foreign-library
    form anymore.
  - defcvar's syntax changed.
  - foreign-funcall can't funcall pointers anymore. Use
    foreign-funcall-pointer for that.

- Fixed the port to architectures without dynamical FFI.
- Tests with too large number of arguments (> 34) are marked as
  expected to fail.

- Use pathname-device and pathname-host to more accurately get
  the current directory on, for example, windows.

Bug report and initial fix by Yaroslav Kavenchuk.

- cffi-ecl fixes:
   - push cffi-features:unix on darwin too.
   - use si:load-foreign-module instead of ffi:load-foreign-library
     on DFFI platforms.
   - use convert-external-name in foreign-symbol-pointer.
- wrap defcvar's define-foreign-symbol around eval-when.
- simplify default-library-suffix
- cffi-tests:
   - load libtest.o on ECL platforms without DFFI.
   - conditionalize the tests with 127 arguments based on the
     value of lambda-parameters-limit.

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

- update dll version.
- add some CMUCL/darwin failures.

- Export 'float_min', 'float_max', 'double_min', and 'double_max' from
  the libtest shared library with the values of FLT_MIN, FLT_MAX,
  DBL_MIN, and DBL_MAX, respectively.
- Use *FLOAT-MIN*, *FLOAT-MAX*, *DOUBLE-MIN*, and *DOUBLE-MAX* as test
  values for foreign floats/doubles instead of the Lisp constants
  <foo>-POSITIVE-<bar>-FLOAT.

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

- extend load-foreign-library to accept a pathname as an argument.
- change tests/bindings.lisp to pass a pathname.

Well, support for asdf setups that don't put fasl files next to
the source files. The Makefile will delete the .fasls directories
on make clean (that's where my setup puts the fasls) and bindings.lisp
will save the shared library's location at compile-time.

- defcvar now works (more) correctly with aggregate types.
- struct types now carry alignment information which is now
  correctly calculated (for unions too) according to the x86
  ABI (tested on darwin/ppc too, but should study other ABI
  docs at some point).
- also tail padding is now correctly added to structs, when
  necessary. (also according to the x86 ABI).
- 4 new tests for this struct bug (reported by Wilco Greven).
- tweaked tests/bindings.lisp to correctly load the library on
  Lispworks and to make it more portable across win/nix/etc..

... in order to work with the MSVC++ free toolkit.

- correctly load the test library.
- and __declspec(dllexport) to the test library functions
- implement a strdup, used in 2 tests
- added a compile.bat, the free toolkit doesn't seem to have
  nmake. Also, I don't know how to make ASDF automatically
  compile the lib under win32 like I did for *nix.
