Has anyone experienced this problem when using g++ and X11R4?

In the header file Intrinsic.h, a type String is declared.  Whenever I compile
xmenu1.cc (an R4 example program) I get a parse error at line 102.  I think
there might be a conflict with the String class in libg++.  But I don't
include any libg++ header files!

Intrinsic.h
------------
#define XtNumber(arr)		((Cardinal) (sizeof(arr) / sizeof(arr[0])))

typedef char *String; <============= line 102
typedef struct _WidgetRec *Widget;
typedef Widget *WidgetList;


 // Program begins here	
 // A simple Simple Menu Widget example.
 // xmenu1.c  -- From the X11R4 examples directory
 // Copyright removed because I got tired of looking at it
