I'd like to update my Cygwin environment installed for all users
without administrative priviledge. Setup.exe seems to work in
this case, but doesn't take account of the system mount table.
The following patch can fix it.

2001-11-11  Kazuhiro Fujieda  <fujieda AT jaist DOT ac DOT jp>

	* mount.cc (read_mounts): Allow reading system mount table without
	administrative priviledge.
