checking whether build environment is sane... s-parame.ads:96:51: value not in
range of type "System.Parameters.Size_Type"
s-parame.ads:96:51: static expression fails Constraint_Check

Line 96 is this:
  Default_Env_Stack_Size : constant Size_Type := 8_192_000;
   --  Assumed size of the environment task, if no other information
   --  is available. This value is used when stack checking is
   --  enabled and no GNAT_STACK_LIMIT environment variable is set.

I think this is because the H8 only has a limited address range and 8MB is too
large for its default environment stack size.  I am recalling that 64K is 
the limit for offsets and that the larger parts in the family only have 24
address bits for 16MB.

Ada not boehm-gc.  Selected wrong box.

Laurent.. would it make sense to have a "low memory" alternate version of the
file in question and swap it in on some targets like the sh2e issue?

First you need to find out which stack_size works on your target.

An obvious patch would be something like that:

Default_Env_Stack_Size : constant Size_Type := Size_Type'Min (8_192_000,
Size_Type'Last / 1024 );

Otherwise since the only used of Default_Env_Stack_Size is s-stchop.adb I think
replacing the constant by a function would be acceptable, then you could
customize the return value it in s-parame-rtems.adb.
