On the mainline (20030821) we get a warning which looks wrong:
pr8420.c:12: warning: declaration does not declare anything

In C99 mode I also get an warning about the 2nd struct and the 3rd:
Perf-Evals-Computer:~/src/gccPRs peg$ ~/fsf-clean-nocheck/bin/gcc pr8420.c -std=c99
pr8420.c:6: warning: declaration does not declare anything
pr8420.c:10: warning: declaration does not declare anything

For C99 mode it is right to rejct it as there are no such things as anonymous structs.
