I don't see how that can be happening.  Look at the case statement immediately
below the code in question.


enable_threads_flag=$enable_threads
# Check if a valid thread package
case x${enable_threads_flag} in
        x | xno)
                # No threads
                target_thread_file='single'
                ;;
        xyes)
                # default
                target_thread_file=''
                ;;
        xdecosf1 | xirix | xmach | xos2 | xposix | xpthreads | xsingle | \
        xsolaris | xwin32 | xdce | xvxworks)
                target_thread_file=$enable_threads_flag
                ;;
        *)
                echo "$enable_threads is an unknown thread package" 1>&2
                exit 1
                ;;
esac


It seems to me that without your patch x${enable_threads_flag} will expand
to "x", which should match the No threads clause.  If that's not working
correctly, you need to explain why.

Also, do not send patches to configure, it is a generated file from 
configure.in and other files.
