Do I need to #define GLIB_CHARSETALIAS_DIR ?

[John Emmas <john creativepost co uk>]

I'm building glib (from git master) using MSVC (using my own VC 
projects). This morning I noticed a change at line 68 in 
'glib/libcharset/localcharset.c'

Previous code:-
      /* Get LIBDIR.  */
      #ifndef LIBDIR
      # include "configmake.h"
      #endif

New code:-
      /* Get GLIB_CHARSETALIAS_DIR.  */
      #ifndef GLIB_CHARSETALIAS_DIR
      # include "configmake.h"
      # define GLIB_CHARSETALIAS_DIR LIBDIR
      #endif

My MSVC build is now failing because 'configmake.h' doesn't exist on my 
system.  Do I need to get it from somewhere?  Or do I need to #define 
GLIB_CHARSETALIAS_DIR to something?  Thanks,

John
(P.S. I'm not using 'make' BTW).
