M_PI not being found in math.h with gtk

[zentara <zentara1@xxxxxxxxxxxxx>]

Hi,
Can someone please explain this oddity, or are my libsmessed up.  I have glib-2.12.9  and  gtk+-2.10.8
In normal c, I can --------------------------------------#include <stdio.h>                                                           #include <math.h>                                                                                                                                         int  main (){                                                                printf("%f\n",M_PI);                                                         return 0;                                                                    } ------------------------------------Output:3.141593

However, when I use the gtk libs----------------------------------------------------------------#include <math.h>                                                            #include <gtk/gtk.h>                                                                                                                                      int  main (){                                                                                                 g_print("%f\n",M_PI);                                                                                                                                   return 0;                                                                    }  -------------------------------------------------------------
I get errors error: ‘M_PI’ undeclared 

Thanks for the enlightenment,zentara
