Compiling lib/irs/getnameinfo.c:

getnameinfo.c: In function ‘irs_getnameinfo’:
getnameinfo.c:133:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
   if (result != 0) goto cleanup; \
      ^
getnameinfo.c:322:4: note: in expansion of macro ‘ERR’
    ERR(EAI_INSECUREDATA);
    ^~~
getnameinfo.c:323:3: note: here
   default:
   ^~~~~~~

I suggest to add a break after the line 322.
