You seem to have made TCC stricter than GCC:
$ cat t.c
typedef int x;
typedef int x;
$ gcc -Wall -O2 -c t.c
$ ./tcc -B. -c t.c
t.c:2: error: redeclaration of 'x'
Apparently such redefinitions are not officially allowed in C99, so
TCC is not really wrong in giving an error, if TCC is only claiming to
be a C99 compiler, but they are allowed in C11, so it may turn out to
be rather impracticable to be so strict...
