I disagree; I've seen too many examples to the contrary.

I suggest the following approach to the multi-config case:

  - detect it (look for "%config%", and make sure you compare
    case-insensitively, as many people right %Config% etc.);

  - ask the user to which configurations they want to add the DJGPP
    setup, and allow to say ALL or give a list;

  - for each configuration name, go to the end of the autoexec.bat and
    add something like this:

      if "%config%"=="CONFIG-NAME" PATH C:\DJGPP\BIN;%PATH%
      if "%config%"=="CONFIG-NAME" set DJGPP=C:\DJGPP\DJGPP.ENV

You will still need to find out if there are any lines that invoke
other batch files not through CALL (in which case the end of
autoexec.bat is never reached), but you need to deal with this
anyway.

The above still has some cases not covered, but those would be rare
(in my experience).

You cannot do that in many cases, since configurations are not
necessarily disjoint.  For example, the following case is very common:

   @echo off
   if "%config%=="simple" goto simplecfg
   ...
   ...
   :simplecfg
   ...

In these cases, the common part is after the :simplecfg label.

I think the installer should be as non-demanding on system hardware
and software as it can.  A simple ASCII interface would be the best
approach for the first approximation.  Once you have the basics
working, you can add bells and whistles.  There's nothing as
frustrating as a runaway installer with a cute display...
