(1) I think this environment control file is a good idea.  But:

(2) DJ doesn't want to do it.  He has enough to do without putting every
    improvement into gcc that's suggested.  I don't want to do it right
    now either.  Nevertheless:

(3) Gcc is provided in source form and can compile itself, so you can
    change it yourself.

    It wouldn't be hard to do what you want.  Gcc reads all environment
    information via a single routine, getenv(), which is part of the
    standard C library.  You simply need to write a special version of
    this which reads the needed environment info from the actual
    environmenf or the .CFG file as desired.

    I recommend that there be a single environment variable (DJGCC ?) to 
    specify the location of the .CFG file.

    All this could posted to the group as a patch.

Good Luck: (Please pardon small flames (8-)).
