For some reason, all of the compilers based on the AdaMajic
front end (ObjectAda and Green Hills Ada 95..Possibly more) want a function
or procedure spec used in conjunction with the pragma inline. So
if you are trying to inline a visible procedure/function in a packake
spec no problem just put the inline in the spec (this is the same
as most (all?) other compilers). WHere it gets cumbersome is that it
wants you to create a useless spec even for cases where you dont really
need one. So for example if the above was in a package body do this.

    function Has_Trail (T : Trail) return Boolean;
    pragma Inline(Has_Trail);


    function Has_Trail (T : Trail) return Boolean
    begin
      return T.Start_In;
    end Trail_Is_In;

 
It is silly and a little annoying but it appears to work. (which is
the most important thing)
