%locations C output in 2.1

[Jim Michaels]

in version 2.1, the output you get from doing a 
%locations
I don't know if it is supposed to do only C++ output or not, but under C output 
it produces the following uncompilable C code, which appears to be a direct M4 
macro.

b4_pure_if(,
extern YYSTYPE b4_prefix[]lval;)

b4_location_if(
#if ! defined (YYLTYPE) && ! defined (YYLTYPE_IS_DECLARED)
typedef struct YYLTYPE
{
  int first_line;
  int first_column;
  int last_line;
  int last_column;
} YYLTYPE;
# define yyltype YYLTYPE /* obsolescent; will be withdrawn */
# define YYLTYPE_IS_DECLARED 1
# define YYLTYPE_IS_TRIVIAL 1
#endif

m4_if(b4_pure, [0],
[extern YYLTYPE b4_prefix[]lloc;])
)
