Q:

map windows file system to unix style

On my dev box I have windows and the prod box is linux, one of the configuration file path points to c:\xxx\test.conf and /home/xxx/test.conf respectively.   
would it be possible to map c:\xxx to a unix style file path /home/xxx on windows
in other words, emulate unix style file system on windows

A:

You can use cygwin, it performs such path mapping inside it.
