I guess, I know why :)

When comparing automake-1.8.5's config-ml.in to my config-ml.in shipped
with RTEMS (Derived from an older gcc's config-ml.in, hacked to work
with autoconf >= 2.57), I found this:

 ml_config_shell=${CONFIG_SHELL-/bin/sh}

 do
   case $option in
+# Unquote autoconf >= 2.57 added quotes
+  \'--*\') eval option="$option" ;;
   --*) ;;
   -*) option=-$option ;;
   esac


Now, the question is who and how to fix it.

IIRC, automake retrieves config-ml.in from gcc.
The origin of the quoting is autoconf.
The file is shipped with automake.
