	I think you are doing things the hard way. Use gnatmake,
that will make your life a lot easier. For instance, if you want
to compile your ada-program.adb which make a call to Foo, which
can be found in libFoo.a library, you can just type:

	gnatmake ada-program --largs -lFoo

	Of course, this assumes that -Foo can be found in the default
library path. For more options of gnatmake, just browse the file
gnatinfo, which you should have got with your Gnat distribution.

	Good luck!!!
