(I agree this thread is getting too long, so we are all tired.)
I want to use this:
IFS=-
set $ac_cv_$1
AC_SUBST([$1_cpu], [$[1]])dnl
AC_SUBST([$1_vendor], [$[2]])dnl
shift; shift
AC_SUBST([$1_os], [$[*]])dnl
If $ac_cv_$1 started with "-", set would misinterpret it as option.
And if it had less than 3 fields, the shifts would complain.
Since both of these are invalid anyway, I want to filter them out.
Regards,
Stepan
