The problem is that gcc before 2.8 did NOT look in any directory relative 
to $DJDIR.  It was *forced* to look inside $DJDIR/* by setting 
environment variables in DJGPP.ENV.

This makes problems with 2.8.x, since directories set by the environment 
variables are searched *before* the built-in ones.  So, if DJGPP.ENV is 
left as it is in v2.01, gcc 2.8.x will look in $DJDIR/* first, and find 
there wrong files.

This is IMHO unacceptable.  The *_PATH variables are meant to allow users 
to augment the search tree with directories specific to the local setup.  
We cannot deprive them of this freedom.

It just so happens that gcc before 2.8 was set up by using those 
directories, because we couldn't trust the compiled-in defaults.
