IMHO, the fix should be in __solve_symlinks.  findfirst/findnext are 
more-or-less direct interfaces to DOS system calls, with no simple 
equivalent on Posix systems, and DOS barfs when there are excess ".." in 
the file name.  The feature whereby "/.." is equivalent to "/" is a Posix 
feature, so we should emulate that in the Posix layer.  Pure DOS 
functions such as findfirst should behave like DOS does.
