Thanks for testing.

Could you perhaps step with a debugger through w32_select_active_frame
and see if this call:

   status = GdipImageGetFrameCount (pBitmap, &pDimensionIDs[0], &frameCount);

returns a value of 'status' that is something other than 'Ok'?  It
returns Win32Error here, for some reason.  If it does return
Win32Error for you as well, what does this show if you type it in GDB
immediately after the call:

  (gdb) p w32_last_error ()

Here it shows zero, which is... not helpful :-(

Right, and "./configure --help" also had it backwards.  Fixed, thanks.
