I gave a possible SHELL_QUOTE definition for sh-style quoting in
previous mails.
If make would define this by default and apply it automatically when
substituting a variable in a recipe, the recipe could simply look
like this, without any explicit quoting:
%.x: %.y
process $< -o $@
Which make internally would turn into:
process $(call SHELL_QUOTE,$<) -o $(call SHELL_QUOTE,$@)
So when calling make "a b'c<d.x", make would e.g. call:
process 'a b'\''c<d'.y -o 'a b'\''c<d'.x

If SHELL_QUOTE is applied automatically, the built-in rules need no
modification because they don't contain explicit quoting either.
Now, if you want to use another interpreter with different quoting
rules, you can do:
SHELL = /bin/frob
SHELL_QUOTE = $(subst or whatever ...)
