I don't think that this is possible. The POSIX emulation in MSYS (or bash, dunno) always converts to POSIX style:

> bash -c "cd c:/temp; PWD=$(pwd -W); echo $PWD; cd $PWD; pwd; echo $PWD"

c:/temp /c/temp /c/temp

That is, even if I use Windows style path to chdir around, the result is POSIX style.

Doing that is certainly not something that I would be prepared to do just to make the bash prompt work right ;-) And the added maintainance burden incurred by the status quo is certainly much cheaper than yet another fork of MSYS and/or bash.
