you could just use the C pre-processor, but I've never really seen anything
that you
couldn't do in Ada - one trick I use is to always have a package called
'Project' which
contains the same details about a project as constants and let the compiler
then
work out which branches that can't be reached. For difference configurations
this
should be the one of the few files then needing changed.

e.g.

package Project is
  Name : constant String := "Blah";
  type An_Endian is (Little_Endian, Big_Endian):
  Byte_Endian : constant An_Endian := ...;
  type A_Processor is (X86, PowerPC, ARM);
  Processor : constant A_Processor := Power_PC;
  -- etc
end Project;
