+Subject: [PATCH] srvkm/env/linux/osfunc.c: fix gcc8 stringop-truncation error
+
+gcc8 now checks for strncpy function that potentially truncate the terminating
+NUL charcter from the source string. Fails like this:
+
+.../services4/srvkm/env/linux/osfunc.c:3051:13: error: 'strncpy' specified bound 50 equals destination size [-Werror=stringop-truncation]
+|              strncpy(psEventObject->szName, pszName, EVENTOBJNAME_MAXLENGTH);
+|              ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+| cc1: all warnings being treated as errors
