This isn't ${cross-prefix} (which will be empty, should cause you no
problems).

You're having trouble with your project settings ... I'm using a
supported version, and on Linux, but try this ..

Go to Ada->Project->Edit, click on Ada menu. You should see something
like

...
Compiling a single file (menu Ada->Compile File):     [Help]  (comp_cmd)
[INS][DEL] cd ${build_dir}
[INS][DEL] ${cross_prefix}gcc -c -g -O2 -gnatqQ -I${src_dir} ${full_current}
[INS]

(your Windows version may say for the first line
[INS][DEL] cd /d ${build_dir}
)

and each successive line is executed with a && to join them up:

  cd /d c:\Temp && gcc -c -g -O2 -gnatqQ -I. c:\Source\foo.adb

I suspect your problem is that the Windows shell that Emacs is using
doesn't understand the && properly.

If you go to the ada-mode home page at
http://libre.act-europe.fr/adamode/ you'll find a pointer to a mailing
list, however it doesn't seem to have been used for a while .. worth a
try.
