I don't think so. Clearly aws.gpr does not know about
test_word_buffer.adb.

I don't think there is a project file syntax for "use this library
for all executables". Perhaps there should be.

One solution is to use 'pragma Linker ("-laws")' in the Ada source for aws.

Hmm. Maybe you could do (in aws.gpr):

package Linker is
    for Default_Switches ("Ada") use ("-laws");
end Linker;

Then in a user project file you can do:

package Linker
    for Switches ("test_word_buffer.adb") use
       Aws.Linker.Default_Switches;
end Linker;

Better, but still not automatic.

'gprmake' (in GNAT 5.03a) can build both C and Ada code, and link them
together. But that's not quite what you want here, I think.

Maybe I've missed something; how do you expect the project file to
work here?
