Max, Trevor,

BASH keeps an internal idea of the current working directory. In the 
face of symbolic links, this internal record of the current working 
directory may not be identical to that computed by the "pwd" programs 
traversal-to-root algorithm.

I use this instead of BASH's built-in pwd command:

wd() {
     WD="$(pwd)"
     WDP="$(/bin/pwd)"
     if [ "$WD" != "$WDP" ]; then
         echo "bash: $WD"$'\n'"real: $WDP"
     else
         echo "$WD"
     fi
}

I use this one if I want to see the Windows form of the current working 
directory, too:

awd() {
     WD="$(pwd)"
     WDP="$(/bin/pwd)"
     if [ "$WD" != "$WDP" ]; then
         echo "bash: $WD"$'\n'"cyg:  $WDP"
     else
         echo "cyg:  $WD"
     fi
     echo "win:  $(cygpath -w -a "$(pwd)")"
     echo "mix:  $(cygpath -m -a "$(pwd)")"
}
