Way too much to list.  There's a reason why a separate repository
exists.

This question indicates that you are unfamiliar with the process to
submit patches to gcc.  To call it a nightmare would be an euphemism.
Nevertheless, I have taken the first step of assigning my copyright
over to gnu, but have hit a stumbling block on the sheer amount of BS
it takes to get a patch first reviewed and then committed, and I have
a least 50 patches.  There are patches I really want to get into the
codebase, so you can tell how much I'm dreading this if I haven't even
submitted the first one.  As an aside, it's just amazing that after 20
years, the gcc group has a whole don't recognize this to be a big
enough problem to fix (although some prominent developers due).

More specific answer: The patches I have that gcc wants mostly deal
with *BSD support and gnat improvements.  I don't think they want the
android stuff (yet) anyway.  Even the gcc/android doesn't mean gnat/
android.

Likely just c/c++

Nothing at the moment.  Maybe somebody could produce some templates to
allow native Ada programs to interface with the android API.  I think
one can make android apps without using java at all, but it requires
binding to the c-interface and all that needs to be developed.

People have build GNAT-AUX on Linux, although personally I was unable
to do it on ubuntu using the gnat from synaptic as the bootstrap.
Linux isn't a focus of GNAT-AUX because Adacore makes sure it works on
Linux.  GNAT-AUX is meant to service the *BSDs and Solaris.
Theoretically it builds on everything that stock GCC builds on, I just
don't test it to verify.
