I've done several developments for Windows drivers where some of the 
driver source was shared with Linux and BSD drivers. The solution we 
came up with was to write a perl build script for the Linux & BSD 
drivers which generated a makefile (in a build directory) from the data
accumulated from the sources files in each directory.
The advantages of this are:
1. only have to modify one file when adding a new source file.
2. Linux drivers can be built using supported mechanism e.g. kbuild for
   linux.
3. Windows drivers are built in DDK environment using dirs/sources
   mechanism as supported by MS.

So this means that the Windows Makefiles are stored in the main source 
tree and the Linux Makefile is generated by a script and is placed in a 
separate build directory.
