 Native comp does not respect byte-compile-warnings
Date: Sat, 6 May 2023 17:52:35 +0100

[Message part 1 (text/plain, inline)]

Yes I'm talking about nativecomp.

Reproduction:

1. (setq package-native-compile t)
2. (setq byte-compile-warnings '(not docstrings
docstrings-non-ascii-quotes))
3. (setq native-comp-async-report-warnings-errors 'silent)
4. M-x package-install ov
5. Observe the differences between the *Compile-Log* buffer and the
*Warnings* buffer.


Jimmy
