[Bug c++/22556] New: extern array: compatible declaration at function scope refused

["SWElef at post dot sk" <gcc-bugzilla at gcc dot gnu dot org>]

extern int foo[]; // OK
int foo[]={1,2,3};
extern int foo[]; // OK

void bar(){
  extern int foo[]; // g++: ERROR -- SHOULD BE OK
}

g++ 3.4.0, 3.4.3, 4.0.0 (cygwin), g++ 3.4.2 (mingw):
xxx.cpp: In function 'void bar()':
xxx.cpp:6: error: type mismatch with previous external decl of 'int foo []'
xxx.cpp:2: error: previous external decl of 'int foo [3]'

g++ 3.3.1, 3.3.2 (cygwin) issue a slightly different error message

This may be related to PRs 21342 and 21502.
