MSVC linker errors (gdk-pixbuf-buffer-queue.c)

[John Emmas <johne53 tiscali co uk>]

When trying to build from the latest git master (using MSVC) I'm seeing 
several linker errors which all take the following form:-

error LNK2019: unresolved external symbol _gdk_pixbuf_buffer_queue_new 
referenced in function _gdk_pixbuf__tga_begin_load
error LNK2019: unresolved external symbol _gdk_pixbuf_buffer_queue_pull 
referenced in function _tga_load_header
error LNK2019: unresolved external symbol _gdk_pixbuf_buffer_queue_flush 
referenced in function _tga_read_info

(and a few others).  I added the new source file 
(gdk-pixbuf-buffer-queue.c) to my MSVC project - and it definitely is 
getting compiled - so I'm guessing that the relevant functions aren't 
yet getting exported..?

Do those new function names need to get added to gdk-pixbuf.symbols?  
Thanks,

John
