I also believe (I could be wrong) that for directories, the only
two methods of links are the Soft link methods above. So PGXLOG
cannot use soft links on a non-XP/2K machine unless it is
"Shell-Aware". For example, in a cygwin bash command window:
mkdir dir1
ln dir1 dir2 <- Error using Cygwin implementation
ln -s dir1 dir2 <- Creates a Shell short-cut (NT4)
echo "Hello" > dir1/test.txt
cat dir2/test.txt
"Hello" <- Cygwin's cat(bash?) is shell short-cut aware
Now, in a Windows NT command prompt:
notepad dir2\test.txt <- Notepad can't find file
notepad dir2.lnk <- Displays link contents
That means for a native port with a different PGXLOG directory
running on NT4, the only choice *using links* is to make the
native port shell short-cut aware.
I could be wrong but I don't think so.
