Have you tried gnatmake -M <main-unit-name> on an up-to-date library?

Here's what the GNAT User's Guide says on the subject:

-M
Check if all objects are up to date. If they are, output the object
dependences to stdout in a form that can be directly exploited in a
`Makefile'. By default, each source file is prefixed with its (relative or
absolute) directory name. This name is whatever you specified in the
various -aI and -I switches. If you use gnatmake -M -q (see below), only the
source file names, without relative paths, are output. If you just specify
the -M switch, dependencies of the GNAT internal system files are omitted.
This is typically what you want. If you also specify the -a switch,
dependencies of the GNAT internal files are also listed. Note that
dependencies of the objects in external Ada libraries (see switch -aLdir in
the following list) are never reported.
