Hi Roger

I very recently had an issue with building gprbuild natively on mingw64
and raised an issue on the AdaCore GitHub repo, which has now been resolved.
(with their input / guidance) and I must say relatively quickly, given
time zone differences between Australia and Europe.

Maybe they can assist you in the configuring gprconfig so as to be able to
use LLVM (it should not be that difficult as I believe LLVM/GGC are 
compatible wrt command line arguments! so it should just be a matter of
replacing ggc.exe with the equivalent llvm.exe somewher in their configs

have a look at their Ada Gems/Blogs or the git repo (specifically the 
share/gprconfig/ xml files) for hints/solutions. You may have to tweak
a xml config file to get GANT/gprbuild to use LLVM
