thanks.

because I think it is already inherited by sub-configures in the environment.
if you think I don't have to strip it, I won't.

thanks.

here is what I have now, and it seems to work:

# <http://thread.gmane.org/gmane.comp.sysutils.autoconf.general/13368>
# strip out -srcdir* & -cache-file*
keep_next=maybe
module_configure_flags=''
for arg in @module_configure_flags@; do
  case $arg in
    *\'*) arg=`$echo "$arg" | sed "s/'/'\\\\\\\\''/g"` ;;
  esac
  case $keep_next in
    yes ) module_configure_flags="$module_configure_flags '$arg'";
      keep_next=maybe; ;;
    no ) keep_next=maybe; ;;
    maybe ) case $arg in
      --cache-file=* | --srcdir=*) continue ;;
      --cache-file | --srcdir ) keep_next=no; ;;
      *=* ) module_configure_flags="$module_configure_flags '$arg'"; ;;
      *) module_configure_flags="$module_configure_flags '$arg'";
        keep_next=yes; ;;
    esac ;;
  esac
done
unset arg
unset keep_next
