Hi,
you can build a view conversion between pretty much anything in Ada including
between types with different sizes, although the compiler warns in this case
and gigi pads the smaller type to end up with the same size.
The attached testcase triggers an ICE at -O or above for one of them:

You are right.
There's a proper fix that utilizes AM_CONDITIONAL and sets LDFLAGS properly
in Makefile.am.

Hi,
For following test case:
