Hmm, here's what that page says - I can't see it saying what you're
suggesting here - am I missing something?:
I don't think so. I think I just confused myself. Reading the docs it
appears that other Windows APIs work as I described, but not this one.
Anyway, after looking at it a bit more, I realized that this code uses
MAX_PATH as basis for its buffer's length limit -- and apparently on
Windows that's only 260, much shorter than MAXPGPATH (1024) which our
own code uses to limit the buffers given to readlink(). So maybe fixing
this is just a matter of doing s/MAX_PATH/MAXPGPATH/ in dirmod.c.
I'll test it.
cheers
