Cygwin symlinks not handled correctly

This bug report will be sent to the XEmacs Development Team, not to your local site managers!! Please write in English, because the XEmacs maintainers do not have translators to read other languages for them. In XEmacs 21.2 (beta45) "Thelxepeia (GTK Inside)" [Lucid] (i686-pc-cygwin) of Thu Mar 15 2001 on PASTON configured using `configure --with-dragndrop --site-includes=/usr/include/w32api --debug=no --error-checking=no' Please describe exactly what actions triggered the bug and the precise symptoms of the bug: I symlink init.el, custom.el and others to a shared FAT partition (I run cygwin and linux on a dual boot machine): lrwxrwxrwx 1 philipa None 48 Feb 26 17:16 custom.el -> /share/home/philipa/.xemacs/custom.el lrwxrwxrwx 1 philipa None 49 Feb 26 17:16 info.notes -> /share/home/philipa/.xemacs/info.notes lrwxrwxrwx 1 philipa None 46 Feb 26 17:15 init.el -> /share/home/philipa/.xemacs/init.el This has shown up a regression in b45 that didn't occur in b37. (file-truename "~/.xemacs/custom.el") => "/share" (file-truename "~/.xemacs/init.el") => "/share" Needless to say, chaos ensues.
