wget on Windows replaces path characters in --directory-prefix -

i'm trying download directory , it's subdirectories website, using wget. reading other questions arrived @ this:

wget -nh --recursive --no-parent --cut-dirs=5 --reject "index.html*" --directory-prefix="c:\temp" http://blahblah.com/directory/ 

however, no mather how try formulate c:\temp, wget creates "@5ctemp" in current directory , download in directory. check documentation no avail. preferably able use environment variable --directory-prefix, eg

--directory-prefix=%prefix% 

looks version of wget you're using (1.8.2) either buggy or old. works newer versions, 1 here:

• wget 1.11.4 gnuwin32
• wget 1.14 osspack32
• wget 1.15 eternallybored.org

for completeness, here's link wget wiki download section.
