Hi again!

I have now tested with testsuite/libffi.call/cls_12byte.c.

Compiling the test with GCC and linking with a MSVC-built ffi-5.dll
works, and building it with MSVC and linking it with an import lib
for the GCC-built libffi-5.dll also works.  Both executables output
the expected:

7 4 9 1 5 3: 8 9 12
res: 8 9 12
7 4 9 1 5 3: 8 9 12
res: 8 9 12

So, both libraries can handle returns of large structures for both
FFI_SYSV and FFI_MS_CDECL.

Neat, if I might say so myself!

Cheers,
Peter
