If the environment variable CDPATH is set, some operating systems print the
directory they changed to after executing a cd command.

openldap's configure script contains expressions like `cd $dir && pwd`
which in fact gives the directory twice, garbling some sed commands later.

One should change aclocal.m4 like this:

  dnl test to see if srcdir already configured
! if test "`cd $srcdir && pwd`" != "`pwd`" && test -f $srcdir/config.status;
then
    AC_MSG_ERROR([source directory already configured; run "make distclean"
there first])
  fi
  ifelse([$3],,

or use a construct like ltconfig:

if test "${CDPATH+set}" = set; then CDPATH=; export CDPATH; fi
