Consider the following code that starting with GCC 4.1.0 generates

But this requires to run the program on the target which is not
possible with a cross-compiler. Or is there a trick to declare
something in Ada that would

Righ
Is there any option to ask GCC to print various size and alignment
info on the target platform? This would be very nice during cross
compilation when one can not run the executables to autoconfigure for
such parameters.
Currently I consider for that a hack like copiling the following source:
