[MiNT] How serious is GCC "cast increases requiered alignment of target type" warning?

["Ole Loots" <ole@monochrom.net>]

Hello, I'm getting the warning: cast increases requiered alignment of
target type when compiling code for 32bpp graphics surface... As I know
old 68000 CPU's did throw an exception when accessing unalgined memory,
I'm in doubt if I should care... the prduced binary should be used with
Coldfire / 68030 CPU (which allows unalgined memory access?), so I believe
I can ignore this warning, or is it fatal to ignore it?

greets,
