Good idea. That's actually the solution working in both gnuplot 4.2 and 4.3.

Cool, your patch (committed to cvs) works fine.
However, I think that the keyword should have preference, not string 
variables:

gnuplot> gif='figure.gif'
gnuplot> set out gif
gnuplot> set term gif
                  ^
     unknown or ambiguous terminal type; type just 'set terminal' for a list

or with "po" variable (abbreviation of "postscript").

I think it may be useful to define
	GPVAL_TERM_DEFAULT
to the default startup terminal name, i.e. the same as the default "pushed" 
terminal. Then we will have e.g.
        GNUTERM = "wxt"
        GPVAL_TERM_DEFAULT = "x11"
        GPVAL_TERM = "postscript"

Then, external programs (Octave) could use either
	set macros; screen=GPVAL_TERM
	set term @screen ...options...
on 4.2 or
	set term GPVAL_TERM_DEFAULT ...options...
on 4.3.
