Looks to me like it passes two arguments: "-m" and "256M -d 4M -r 4M
-l 256k".  Given that, we could add another command-line option -#!
that parses the next argument and treats it as a sequence of
command-line arguments.  Then you could write the line as follows:

#! /usr/local/bin/gforth-fast -#! -m 256M -d 4M -r 4M -l 256k

However, I think that there are Unixes that ignore everything after
the first argument, so this approach would not work there.
