[Lazarus] ARM-WinCE test - DBF

[cc_ at freemail.hu]

I probably do not see the depth of the problem, and this seems to be just 
too easy, but for me this should be done on the compiler level: how about a 
compiler switch which forces the compiler to "think" as if the  "unaligned" 
keyword was there at  the potentially  problematic assignments.  FPC and 
Lazarus aims to have a single source for all platforms, and this is broken 
if you have to change the source for ARM.
