I was building libulz for the first time and I got a bunch of warning like this one:
cc-Os-std=c99-I./include-c-osrc/timelib/msleep.osrc/timelib/msleep.cInfileincludedfrom /usr/include/time.h:25,
fromsrc/timelib/../../include/timelib.h:11,
fromsrc/timelib/msleep.c:1:
/usr/include/features.h:185:3: warning: #warning"_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE" [-Wcpp]
185 | # warning"_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE"
| ^~~~~~~
I'm running Debian GNU/Linux bullseye/sid
What about replacing _BSD_SOURCE occurrences with _DEFAULT_SOURCE ?
