"Pyrenean-pre8" problems on WinNT

The good news: I have XEmacs 21.0 "Pyrenean-pre8" built on Win32/MSVC6.0, with Jonathan Harris' unofficial EFS patches, and it mostly all works beautifully.... The bad news: it doesn't all quite work so beautifully. EFS works fine on my network, but I get these warnings: (1) (warning/warning) Error caught in `make-auto-save-file-name': Creating directory: No such file or directory, c:\home\cgw\home\cgw\/.autosave (HOME is /home/cgw; this is apparently getting doubled up somehow) Updating packages using EFS: XEmacs successfully fetches the .pkg.tar.gz files from xemacs.org, but when they are installed, I get a warning in the *Package Output* buffer: gunzip: stdout: Bad file number and the new package is not installed. Worse, the old files are removed from /Program Files/XEmacs/xemacs-packages and I'm left with no packages at all.... If updating packages via EFS is going to require a gunzip and tar, we better include suitable versions with the Windows distribution. I'm using the gunzip and tar from the Cygnus toolkit (in a non-Cygnus XEmacs) and they seem to be not suitable. Ditto for the FTP.EXE that comes with Cygnus: EFS works with \WINNT\System32\ftp.exe but not with the "ftp.exe" from Andy Piper's "local.tar.gz" distribution.
