Have you tried a Text_IO.Put_Line ?

Also, Its been a while, but I believe there is a "FORM =>" parameter
you can give Text_IO if you are opening or creating a file to specify
no buffering. In fact, I seem to remember that you can do anything RMS 
can do with the right "FORM =>" parameter.

That sounds like the dreaded dependancy problem. You can avoid it by
making sure that in your compilation there are no situations where a 
package in a "child" library depends on a package in a "parent" library 
which in turn depends on a package in a child library. This often happens 
when a commonly "withed" package is brought down to a lower library for
maintanence. 

If I remember correctly, DEC Ada detects this situation and enters links
in your lower-level libraries so that no unit in your compilation depends
on a unit in one of your child libraries. When the maintanence is done
and the unit is moved back up to the correct parent library, you may be
clever enough to remove the unit itself from your library, but the links
that DEC Ada created must be removed as well.
