Hello,

Updated libcurl from 7.12.0 to 7.19.6.
Built libcurl on Linux and Windows XP Pro SP2 (VC++ 6.0).
Linked libcurl to our program.
Basic flow is login, placed in account directory (zzzz), change to out directory (zzzz/out),
download the file, move back to account directory (zzzz), delete the file in the out
directory (DELE out/test.txt). Probably should just delete the file while we are in the out
directory but this code was written many years ago and I am the keeper now and I am trying
not to break anything. Linux version seems to run fine.
Windows version adds a "CWD /" that takes us too high up the directory tree.
No code is changed in our program, just the libcurl version that we link to in VC6,
link to 7.12.0 and it works, link to 7.19.6 and we get the CWD / and a failure.
Logs shown below.

This one works (7.12.0):

< 230 User zzzz logged in.
* We have successfully logged in
> PWD
< 257 "/zzzz" is current directory.
* Entry path is '/zzzz'
* Connection #0 to host xx.xxx.xx.xx left intact

Sorry for the message length, just trying to give all the details.
New to libcurl and this mail list.
Thanks for any help.
