[Bug c++/30745] New: Undefined static const

["hans dot buchmann at fhso dot ch" <gcc-bugzilla at gcc dot gnu dot org>]

Compiling the code

class Class
{
 public:
   Class(const unsigned maxLine);

 private:
  static const unsigned MAX_LEN = 16;
  unsigned max;
  unsigned array[MAX_LEN];
};

Class::Class(const unsigned maxLine)
:max((maxLine<MAX_LEN)?maxLine
                      :MAX_LEN)
{
}

with the command:

g++ -Wall -O0  -fno-exceptions -c -o const-test.o const-test.cc

leaves Class::MAX_LEN undefined:

nm --demangle const-test.o
         U Class::MAX_LEN
00000028 T Class::Class(unsigned int)
00000000 T Class::Class(unsigned int)


The compiler  g++ -v
