I have tried to bind it manually:

--------

using GLib;

[CCode (cname="g_ascii_dtostr", cheader_filename="glib.h")]
private extern string dtostr (double x);

public class DoubleToString {

        static int main (string[] args) {
//              Gtk.init (ref args);
                print ("%s\n", dtostr (3.1415));
                return 0;
        }
}

--------

But this results in an error:


doubletostring.c:12: error: conflicting types for 'g_ascii_dtostr'
/usr/include/glib-2.0/glib/gstrfuncs.h:142: error: previous declaration 
of 'g_ascii_dtostr' was here
error: cc exited with status 256
Compilation failed: 1 error(s), 0 warning(s)

Any ideas?
Thanks
