[Source compatibility suite] swift-power-assert failing to build - Undefined symbols

[xymus]

The swift-power-assert fails to build in the source-combat-suite against main: https://ci.swift.org/job/swift-main-source-compat-suite-debug/487/

The error is on missing symbols, a lot of missing symbols:

@neonichu Since this is not a compiler issue and was fixed in swiftpm, could you transfer it there please?

[neonichu]

This should actually stay open and be transferred to wherever we track compat suite issues. I guess GH automation closed it because I mentioned this issue, that wasn't my intent.

Specifically we need:

• the project itself to make a change: Fix issues with excluding macros/plugins from dependency computation swift-package-manager#6723 (comment)
• re-enable the project in the compatibility suite

[AnthonyLatsis]

Then I believe it should be moved to the compat suite repository. We used to, but I don’t think we want to keep tracking compat suite source/specification issues here.
