What did you do?

I tried to build a project.
This project was previously succesfully built in go 1.14.6 on the same machine.

The interesting thing is I then uninstalled 1.16.2 and reinstalled 1.14.6 and it compiled fine again.
I then kept 1.14.6 and installed 1.16.2 as a second version on my system following these instructions. I was then able to build it with go1.16.2.

So to me it seems like the problem is not in the go compiler itself but in something that go uses.
I found a microsoft article which states that

This function is implemented using a compiler intrinsic where possible. For more information, see the WinBase.h header file and _InterlockedExchangeAdd

Does Go implement this Function itself or does go rely on gcc?
My gcc Version is 8.3.0

I don't really know which part of the project is relying on this function and I cannot share the project source code.
If someone knows how to trigger an include of that function just tell me I'll try to build it then.

What did you expect to see?

succesful build like it was on 1.14.6

What did you see instead?

runtime/cgo(.text): relocation target _InterlockedExchangeAdd not defined
