Right. The Ada 95 sources used the same tool as the Ada 83 sources, with a 
new set of macros.

I just wrote an Ada program to process the existing Ada 95 source code (with 
a few simplifications; mainly, I got rid of all of the macros and the 
support for that). That meant we were no longer dependent on an ancient (but 
powerful) text formatter; anyone with an Ada compiler can build a version of 
my formatter.

It's fairly easy to add a new output module (as Stephen can attest); that's 
the preferred way to make new versions of the Standard, simply because it 
will handle both older and newer editions of the Standard.
