false alarm with 'gcc -O2 -S -Wreturn-type'

Attached is the third and final example I got from Coreutils today. When I
compile it it with 'gcc -O2 -S -Wreturn-type' I get the following false alarm:

noreturn2.c: In function ‘find_int’:
noreturn2.c:15:1: warning: control reaches end of non-void function
[-Wreturn-type]
   15 | }
