commit daab2d3a62ac8fb1c74987e614cee93dc79fab74
Author: Paul Eggert <address@hidden>
Commit: Paul Eggert <address@hidden>
Fix typos in recent attribute.h simplification
Problem reported by Andreas Schwab in:
https://lists.gnu.org/r/emacs-devel/2020-05/msg00650.html
* src/conf_post.h (HAS_ATTR_no_sanitize): Define to false in case
cpp is picky, fixing a longstanding glitch here.
(ATTRIBUTE_NO_SANITIZE_ADDRESS, ATTRIBUTE_NO_SANITIZE_UNDEFINED):
Use HAS_ATTRIBUTE, not __has_attribute.
