Comment 1 for bug 622339

This happens with a recent ccl under linux 32 bits env, and not occure under linux 64, etc.
By this wrong alignment problem, for example, cl-gtk2's demo crashes.
The reason is very clear. As you know, gcc under linux 32 has 64 bits alignment for the long-long type. But
there is an exception that, in a struct or union, it becomes 32 bits alignment. However,
ccl:foreign-type-alignment always returns 64 for the long-long type (of course, it is theoretically true
and internally ccl uses proper alignment (=32) for the record type).

Therefore the following patch is needed:
*** ./src/cffi-openmcl.lisp.org 2012-09-25 00:48:14.000000000 +0900
--- ./src/cffi-openmcl.lisp 2012-09-25 00:51:09.000000000 +0900
