Not for me.
% mkdir /boo

$ ls /boo/..
bin cygwin dev localhome proc usr
boo cygwin.bat etc netrel sbin var
cygdrive cygwin.ico home netrel.build share
cygmount.bat Cygwin-Terminal.ico lib netrel.inst tmp
norton[~]
% cygpath -m /boo/..
D:/cygwin
It doesn't work if boo is not a directory but that is as expected.

nonexistent or non-directory. We've fixed a bug in later versions of Cygwin
which this script relied on.
It could be rewritten as:
CURRENT_DIR=$(cygpath -ma "$(dirname $0)")
(assuming that CURRENT_DIR isn't really trying to find the cwd, in which
case the script is just wrong to begin with)
