Directories have nothing to do with what you are seeing.

../libtool is equivalent only to ./libtool on the parent directory, what
you did was execute the first libtool found on the PATH, to see which
one is it try "which libtool".

Of course if PATH contains . before any other directory then things
would work as you expect, except that the libtool you are testing still
doesn't output anything, is that libtool compiled to be a windows app?
many windows console applications don't interact well with Cygwin,
output is buffered and shows much later than expected, or doesn't show,
windows pipes don't connect, etc. and things changed even more if you
are using Cygwin 1.7 (works worse now).
