---------

-This section provides several hints that have been submitted by LyX
-team members or users to help compiling on some particular
-architectures. If you find that some of these hints are wrong, please
-notify us.
-
-  o On SUN Sparc Solaris, you need gnumake. The LyX makefiles do not
-    work with Solaris make.
-
-    The Solaris 8 ar seg-faults trying to build the insets library. You
-    will need to use the ar from the GNU binutils for this subdirectory.
-    There is no problem with the Solaris 9 and 10 ar.
-
-    Qt4 uses the Xrender X11 extension for antialiased fonts. This
-    extension was added to Xsun starting from the Solaris 10 8/07
-    release, but it is not activated by default. To activate it, you
-    must issue (as root) the following command:
-    svccfg -s svc:/application/x11/x11-server setprop options/server_args=+xrender
-    and then restart the X server.
-
-    There is a problem with the fontconfig library shipped with
-    Solaris 10 8/07 causing a seg-fault when it is used by Qt4.
-    Until this is fixed, a workaround is replacing the shared library
-    /usr/lib/libfontconfig.so.1 with a copy from a previous release or
-    installing a new version of fontconfig from http://www.sunfreeware.com/
-
-    On Solaris, the default fontconfig configuration gives preference
-    to bitmap fonts at (not so small) sizes. As bitmapped fonts are not
-    antialiased, you may prefer changing this configuration. This may be
-    done by adding the following stanza
-
-          <match target="pattern">
-              <edit name="prefer_bitmap">
-                  <bool>false</bool>
-              </edit>
-          </match>
-
-    to either ~/.fonts.conf (for a per-user change) or /etc/fonts/local.conf
-    (for a global system change). The stanza should be added between the
-    <fontconfig> and </fontconfig> tags. If neither ~/.fonts.conf nor
-    /etc/fonts/local.conf exists, you can create them with the following
-    content:
-
-      <?xml version="1.0"?>
-      <!DOCTYPE fontconfig SYSTEM "fonts.dtd">
-      <fontconfig>
-          <match target="pattern">
-              <edit name="prefer_bitmap">
-                  <bool>false</bool>
-              </edit>
-          </match>
-      </fontconfig>
