Re: Need GNAT Help !!!!!

[samw@wwa.com (Samuel G. Williams)]

What we are attempting to do now because of the way in which the code was
written is leave integer as a universal value and change the actual size
of the integer within the gnat environment. I know this sounds hokie, but
the end application is written only for an embedded 80186 and this is a
pilot use of gnat. If this works things will be changed to the more normal
method of creating special data types for our applications. Our problem
should have beeb realized up front, but unfortunately it wasn't. By the
way, this is for a special lab application and not one that will be flying
in the next Boeing release. 

You also mentioned something about the byte ordering differences betwwen
sparc and 80186. do you know of any reference documentation that
illustrates this.

I really appreciate all help and comments I have received. Any additional
will be greatly appreciated.
