From 6c7b71324963228521d74b3b4aec5a65b9ea89aa Mon Sep 17 00:00:00 2001 From: Bertrand Drouvot Date: Fri, 24 Mar 2023 08:37:29 +0000 Subject: [PATCH v1] Generating waiteventnames.h, waiteventnames.c and waiteventnames.sgml Purpose is to auto-generate those files based on the newly created waiteventnames.txt file.
