FS#674 - strict-aliasing warnings with gcc-4.4

----------
There's still several places where a reinterpret_cast is used. Since you can only use this in rare cases without violating the rule, we should go through all of the uses and check if they are standard conforming. If they are not we should replace them if they are we should add a short documentation why it's OK here for later reference.

For example there seem to be several places where some raw C array is casted to a FieldVector which is in my impression a violation (even if there's no warning with current compilers).
