m4_foreach_w and "options"

[Vincent Torri]

Hey

usually, when we want to write an m4 macro that will be used like that:

my_macro([foo1 foo2])

we can use m4_foreach_w:

AC_DEFUN([my_macro],
[
m4_foreach_w([fct], [$2], [my_check(m4_defn([fct]))])
])

But I would like to write am m4 macro that would be used like that:

my_macro([foo1 foo2], [bar1 bar2])

and I would like to "associate" bar1 to foo1 and bar2 to foo2 (bar* would 
options for the macros called by m4_foreach_w() in my_check (see above)), 
that is

for foo1, my_check would be called with bar1
for foo2, my_check would be called with bar2

is it possible ?

thank you
