The important thing is to find the file where the compiler will find it!

GCC, I think, uses the first occurrence of a file on its search path.  
gnatmake, however, insists on there being only one file on the search  
path for the project (unless you are extending another project).

It would be quite normal for us to have:

spec in directory X
body (with body stubs) in directory X
proper bodies and some handwritten source in directory Y

and then replacement ('patch') proper bodies in directory Z.

So it's not that simple .. but with about 500 directories and 19_000  
source files, it typically takes less than a second on a 3 GHz Windows  
box to get to the right place (that's using AdaCore's GLIDE; but the  
general mechanism is the same, I feel their convert_prj utility is  
quite fast compared to gnatpath but no timings to hand),
