I just removed the "overriding" on the "=" operator, since that was rejected by the x64 compiler.
It amazed me that it actually compiled before with 6.2.2 because is is just a function and not an
Overriding operation on a tagged type.

Understand. I have incorporated the AWS sources in my own build which simplifies the build
for our engineers. I should have looked into this.

I still forgot another patch in zlib.
I found that zlib actually comes directly from the zlib distribution.
To make zlib work I have made the patch as shown below.
I do however not have a good explanation why it it needed.
If this fix is not present, the size of the ada record is different then the one in the C code on x64
and zlib will check on that in the C code.
This fixes that problem.
Not sure this is somehow a compiler problem.

Greetings,

Wiljan
