Elaboration circularity

[Frode Tenneboe <ft@alne.edh.ericsson.se>]

I am currently looking into some legacy code which is heavily nested
with cirular dependencies. Compiling with gnat give the following message:

gnatbind -x client.ali
error: elaboration circularity detected
info:    "edhipc (body)" must be elaborated before "edhipc (body)"
info:       reason: Elaborate_All probably needed in unit "edhipc (body)"
info:       recompile "edhipc (body)" with -gnatwl for full details
info:          "edhipc (body)"
info:             is needed by its spec:
info:          "edhipc (spec)"
info:             which is withed by:
info:          "edhipclog (spec)"
info:             which is withed by:
info:          "edhipc (body)"
gnatmake: *** bind failed.
*** Error code 4
make: Fatal error: Command failed for target `client'

As you can see edhipc.adb is referring back to itself. So - I have
to unroll this mess. Are there any handy tricks when doing this?
The exact approach depends of course on the actual software, but
is it generally better to move the code out into new package(s) or
remove the circularity?
