Build Fails With GCC/GNAT 10.3.0 #323

https://github.com/AdaCore/aws/blob/fbf2f209ea25817859e54220d287eccaf2d6ae61/src/http2/aws-http2-frame.adb#L49

I'm attempting to build on Ubuntu 21.10 using the following dependencies: build-essential git unzip xsltproc liblzma-dev libssl-dev libcurl4-openssl-dev git gnat gprbuild libgnatcoll19-dev

I ran make SOCKET=openssl setup which succeeds and make build which fails with the following:

#10 2.497    [Ada]          aws-http2-hpack-table.adb
#10 2.521    [Ada]          aws-http2-message-list.ads

Probably an incompatibility between the GCC/GNAT compiler and the AWS version.

I'm assuming that GCC version is better at detecting unnecessary use clauses. Looking at the .gpr it doesn't seem like it should treat that as an error unless targeting a debug library; which it doesn't seem like the make command should be doing by default. I have yet to look into that more.
