That's just plain wrong. If you had actually bothered to try it, you would
have found that gcc with your recommended options accepts the original
code (as permitted).
$ gcc -W -Wall -ansi -pedantic testit.c -o testit
testit.c: In function ‘main’:
testit.c:5: warning: ISO C forbids nested functions
testit.c:10: warning: ISO C forbids nested functions
testit.c:18: warning: control reaches end of non-void function
$ ./testit

Implementations aren't required to reject code with syntax errors or
constraint violations. GCC with your recommended options doesn't. This is
intentional, conforming, and documented.
