Implementing such a thing would be fairly easy.  But, I think
the point here was that in order to do this, the x11 terminal
would have to be the current terminal.  That is

set term x11
plot sin(x)
set term postscript
raise 1

might not work because after doing the "set term postscript"
the terminal pointer in not pointing to x11 anymore.

It sounds to me that the strategy here is to now break the
terminals into two classes, the normal group of terminals and
a visual GUI set of terminals, i.e., the terminal in which one
is viewing interactively.  The "raise" would only apply to the
interactive terminal.  That means that the source code should
have an addition terminal pointer, say interactive_term, that
the raise command operates on.  (I'm also arguing that if you
are going to go through this trouble, the function should be
more than just raise... also minimize, maximize, close, hide, etc.)
Would it be possible to configure Gnuplot's compilation so that
it can figure out which terminal should be the "interactive" one?

How about this idea?  Say the GUI-based terminals (x11,
Windows, pm, etc.) have an option called "interactive", e.g.,

set term x11 interactive

This will set the hypothesized interactive_term variable.  (If the
compilation is only for x11, perhaps interactive_term should have
a default of the x11 terminal.)  Then "raise" will send the required
terminal command to that, so that if one types "set term postscript",
any raise commands still go to the x11 terminal.  If interactive_term
is zero, then the command gets sent to the current terminal, which
in some cases will be an empty function.
