Building cyrus-sasl with GCC 14 fails here:
https://build.opensuse.org/package/live_build_log/openSUSE:Factory:Staging:Gcc7/cyrus-sasl/standard/x86_64
Or built using:
osc build --alternative-project openSUSE:Factory:Staging:Gcc7

Due to:

saslutil.c: In function ‘sasl_mkchal’:
saslutil.c:280:3: error: implicit declaration of function ‘time’ [-Wimplicit-function-declaration]
  280 |   time(&now);

saslutil.c:66:1: note: ‘time’ is defined in header ‘<time.h>’; this is probably fixable by adding ‘#include <time.h>’
