If we assume that $2 is a literal `yes' or `no', i.e., the value can

Well, in that case Vincent should use $2 in the argument to
AS_HELP_STRING, not $wanted_value. Sorry for not reading close enough.
ok. I will change the value of $2 to be "enabled" or "disabled",
instead of "yes" or "no".
There is no need for that.
You can choose different strings at m4 time (i.e., at autoconf run time)
if that's your point. You just can't use shell code for this, because
it is run way later, at configure run time.
Use something like
m4_if([$2],
[yes], [enabled],
[no], [disabled],
[unknown default])
in the argument to AS_HELP_STRING.
ok, i'll try that. Thank you
Another related question : if i call ECORE_CHECK_MODULE() several
times, only the first help is displayed when i run ./configure
--help. Is it because i use m4 macro ( []m4_defn([DOWN] ) in the 1st
argument of AC_ARG_ENABLE ?
Sounds like an m4 quoting bug somewhere. Please show small example code
to reproduce.
the smallest example is the one i gave in the first mail ;)
