Hm, the INSTALL file states:


To disable individual types of image support in Emacs for some reason,
even though configure finds the libraries, you can configure with one
or more of these options:

  --without-xpm          for XPM image support
  --without-jpeg         for JPEG image support
  --without-tiff         for TIFF image support
  --without-gif          for GIF image support
  --without-png          for PNG image support
  --without-rsvg         for SVG image support

Since I did not use --without-rsvg, I interpret this instruction that
svg *is* supported. So 

    1. Either the documentation should be changed or

    2. There is a bug somewhere


In any case, which configuration should I use, if I want to recompile emacs?
