What about using a wrapper around rdmd, so the program is 
executed with an
additional parameter or an environment variable containing 
"FULL_PATH".

When I started with D, I "accidentaly" wrote my own replacement 
script for rdmd
compiling xyz.d with dmd to xyz or calling xyz depending on the 
modification times of the files.
