At this point I found within my environment variables on Windows:
OS=Windows_NT so I created the following in my .gpr file (I have not 
yest looked in Linux, perhaps I shoud add OS=Linux there)

    type OS_Kind is
       ("Windows_NT", "Linux");
    OS : OS_Kind := external("OS", "Windows_NT");

    case OS is
       when "Windows_NT" =>
          for Object_Dir use "./build";
          for Exec_Dir   use ".";
       when "Linux" =>
          for Object_Dir use "./build";
          for Exec_Dir   use ".";
          for Casing     use "mixedcase";
    end case;

The problem now is the casing, that seems not to be available on 
Windows. In Linux it looks like I need it because the standard there is 
"lowercase" Is there an overall .gpr file that all project use in which 
I can add or change that ?
