Gtk2::Gdk::Pixbuf on win32

["T.J. Ferraro" <tjtoocool phreaker net>]

Not sure if this is a problem with the gtk2 bindings or the underlying 
libraries so I figured I'd start here and work my way back. The attached 
script runs fine on linux. However, I get this on windows:

Couldn't recognize the image file format for file 'image.bmp' at 
imagetest.pl line 13.

Which is the line: $pixbuf = Gtk2::Gdk::Pixbuf->new_from_file('image.bmp');

On the perl side: Cairo-1.045, Glib 1.164, Gtk2-1.164
Gtk2 libraries: cairo-1.4.14, glib-2.14.6, gtk+-2.12.8

As an aside, in my production script I call something slightly different 
because the bmp data is already in memory:

$loader = Gtk2::Gdk::PixbufLoader->new;
$loader->write($bmpdata);
$loader->close();
$pixbuf = $loader->get_pixbuf();
$pixbuf->render_to_drawable($fpdraw->window,$fpgc,0,0,0,0,-1,-1,'none',0,0);

But I felt the attached case was more succinct for a demonstration of 
the same issue.

Any help is much appreciated. Thanks.
