I do *NOT* recommend using -malign-double.  It implies an ABI change.  You
can not assume that you can link code compiled with -malign-double to code
that has not been compiled with -malign-double.

Furthermore, the compiler should be doing most alignments automatically, so
there is little benefit in using -malign-double.
