restarting. See the variable `image-library-alist' to configure the
expected names of the libraries.

Binaries for the image libraries (among many others) can be found at
GnuWin32 (http://gnuwin32.sourceforge.net). These are built with
MinGW, and so are very compatible with GCC/MinGW builds of Emacs (like
the official binary tarballs for Windows). Compatibility with MSVC,
on the other hand, is still weak and should not be trusted in
production environments; if you really need an MSVC-compiled Emacs
with image support, you should try to build the required libraries

we'll be interested on hearing of any such effort).
