--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
Confirmed, FE should reject that similarly to:

$ of ‘bar’ was here
 void bar () { }
      ^~~
marxin@marxinbox:~/Programming/testcases> cat pr89340.c
__attribute__((weak))
void bar () { }
bar();

$ gcc pr89340.c
pr89340.c:3:1: warning: data definition has no type or storage class
 bar();
 ^~~
pr89340.c:3:1: warning: type defaults to ‘int’ in declaration of ‘bar’
[-Wimplicit-int]
pr89340.c:3:1: error: conflicting types for ‘bar’
pr89340.c:2:6: note: previous definition of ‘bar’ was here
 void bar () { }
      ^~~
