The binary directories are

    for Exec_Dir use ...;

and (for a library):

    for Library_Dir use ...;

There is no need to specify any (Object_Dir included) unless you build 
for different targets/scenarios, e.g. Debug/Release/Profile and need to 
sort them out.

E.g.

    for Object_Dir use
       "obj" & Target_OS & "/" & Target_Arch & "/" & Development_Type;

As other said, keep you project interoperable between Windows and Linux:

1. Always use small letters
2. Newer use spaces
3. Newer use \ as a directory separator. (GCC and GNAT run-times 
understand /).
4. Newer use Latin-1 or UTF-8 (not even in the string literals).
