The Autoconf manual says: Posix 1003.1-2001 requires that `cd' and `pwd' must update the `PWD' environment variable to point to the logical name of the current directory, but traditional shells do not support this. This can cause confusion if one shell instance maintains `PWD' but a subsidiary and different shell does not know about `PWD' and executes `cd'; in this case `PWD' points to the wrong directory. Use ``pwd`' rather than `$PWD'. so this commit replaces all uses of $PWD by `pwd`. Reported-by: Justin Pettit <jpettit@nicira.com> Signed-off-by: Ben Pfaff <blp@nicira.com>
