Please don't, this is already fixed in GLib dev CVS.

(though I have no clue why the glibconfig.h constants are defined
 with '=' in them -- IMHO it should be " = GLIB_SYSDEF_xxx" in glib.h)

glib.h:
typedef enum
{
  G_IO_IN       GLIB_SYSDEF_POLLIN,
  G_IO_OUT      GLIB_SYSDEF_POLLOUT,
  G_IO_PRI      GLIB_SYSDEF_POLLPRI,
  G_IO_ERR      GLIB_SYSDEF_POLLERR,
  G_IO_HUP      GLIB_SYSDEF_POLLHUP,
  G_IO_NVAL     GLIB_SYSDEF_POLLNVAL
} GIOCondition;

glibconfig.h:
#define GLIB_SYSDEF_POLLIN =1
#define GLIB_SYSDEF_POLLOUT =4
#define GLIB_SYSDEF_POLLPRI =2
#define GLIB_SYSDEF_POLLERR =8
#define GLIB_SYSDEF_POLLHUP =16
#define GLIB_SYSDEF_POLLNVAL =32
