Compiler says it does something that it does not do

[Ty Tower]

Now I will just approach this vewy vewy quietly so no one misunderstands..........

On a Linux machine as user tytower I issue a build command as below . Because I am logged in as user, not root I cannot write to  /usr  so the compiler says I will write to  /home/tytower/d  instead. It does not in fact do this as no directory /home/tytower/d exists or is created ,Even if I create this directory it is not used. It actually write to the current directory which in this case is the same as the directory the program is in.

[tytower at linuxbox MyStuff]$ dsss build -D maintry.d
Default prefix /usr is unwritable, using /home/tytower/d instead.

Now what I am suggesting is that the message out from the compiler is ....wait for it ...wrong. Not that it worries me or there is more I don't understand , but merely to tell someone there that this exits and is ....wrong.
