Mac Mini (2018)
OSX 10.15.5
XCode 11.5
GNAT  Community Edition 2020

Attempting to build git clone git://git.code.sf.net/p/gnoga/code gnoga.

First problem with -gnat05 flag which I overcame but probably not the correct way.
Second, killer, problem:
object-handle.adb:153:22: access attribute cannot be used as actual for universal_access equality
object-handle.adb:163:23: access attribute cannot be used as actual for universal_access equality

How can I fix this?
Thanks for any constructive advice.
