Running 1.36.1, config sun-nfp-0S4, there is bug with static elements 
if structures. Here is a transcript. The source file has two structure
definitions. The first has a static array and the second is
conditionally defined based on the preprocessor value BUG. When this
second structure is not defined, g++ correctly allocates storage for
the static array but fails to allocate storage when the second struct
is define.

dactyl% cat temp.c

struct node {

      static const int            type_size = 6 ;
      static const int stmt_map[type_size] ;

    protected:
      node() { } ;
} ;

const int node::stmt_map[node::type_size] = { 0, 0, 0, 1, 1, 0 } ;

#ifdef BUG
struct expr : public node {
    protected:
      expr() { } ;
} ;
