from what I can see the bogus warning is caused by 

test "$absdir" != "$libdir" && \
func_warning "\`$deplib' seems to be moved"

changing the warning in

test "$absdir" != "$libdir" && \
func_warning "\`$absdir' \`$libdir' \`$deplib' seems to be moved"

I found:
libtool: link: warning: `/usr/lib/gcc/i686-pc-cygwin/4.3.4/../../..' `/usr/lib' 
 `/usr/lib/gcc/i686-pc-cygwin/4.3.4/../../../libfftw3.la' seems to be moved

so it seems that absdir is not a real absolute directory.

and this case block seems the culprit

# We need an absolute path.
case $dir in
[\\/]* | [A-Za-z]:[\\/]*) absdir="$dir" ;;
*)
    absdir=`cd "$dir" && pwd`
    if test -z "$absdir"; then
       func_warning "cannot determine absolute directory name of \`$dir'"
       absdir="$dir"
    fi
    ;;
esac



This assignement would be correct, but it is not applied
absdir=`cd "$dir" && pwd`
