 Since July 1996, most work on Octave has been done using a Linux
 system, and a number of people who regularly test Octave snapshot
 releases also primarily use Linux systems.  Because of this, I believe

 If the location of the correct set of include files is not listed in
 the search path, then you might be able to fix that with a symbolic

-The linker can't find -lieee
-----------------------------
-
-This can happen because your libraries don't match your version of
-gcc.  Some recent Linux distributions don't include a libieee.a file
-because IEEE support is now the default and the library is no longer
-needed, but the gcc specs file still adds -lieee to the linker command
-if gcc is invoked with the -mieeefp flag.  I believe that you should
-be able to fix this by editing the gcc specs file.  In it, you should
-find something like this:
-
-  %{!shared: %{mieee-fp:-lieee} %{p:-lgmon} %{pg:-lgmon} \
-  %{!ggdb:-lc} %{ggdb:-lg}}
-
-changing it to
-
-  %{!shared: %{p:-lgmon} %{pg:-lgmon} %{!ggdb:-lc} %{ggdb:-lg}}
-
-should keep gcc from adding -lieee to the link command.  You can find
-the location of the specs file by running the command gcc -v.
-
-If you can't edit the gcc specs file for some reason, another solution
-that should work is to create an empty libieee.a file in the Octave
-src directory using the command:
-
-  ar cq libieee.a
-
-NOTE: you should fix this problem (either by editing the specs file or
-by creating the library) *before* running configure and compiling
-Octave.  Otherwise, configure may incorrectly determine that your
-system doesn't have support for some IEEE math functions.

-My system doesn't have g77
---------------------------
-
-A binary release of g77 that should work with gcc 2.7.2 is available
-from sunsite.unc.edu in the directory /pub/Linux/devel/lang/fortran.
-There is also a Debian package for g77.  Also, g77 is now included as
-part of egcs (http://www.cygnus.com/egcs).
-
-Problems with g77 on Debian 1.2 systems (and possibly others)
--------------------------------------------------------------
-
-Your best bet is to upgrade to Debian 1.3 (or some newer version).
-If you choose not to do that, here are some old tips for working
-around the problem.
-
-The location of the compiler binaries changed, so the g77 0.5.18
-package can not be used without modification.  The problem is that the
-Debian package was built for gcc 2.7.2 and not 2.7.2.1 and the f771
-backend is installed in the wrong directory.
-
-Version 0.5.19 of g77 has just been released.  A fixed Debian package
-may be made available soon.  Until then, you can make things work by
-copying f771 and libf2c.a from /usr/lib/gcc-lib/i486-linux/2.7.2 to
-/usr/lib/gcc-lib/i486-linux/2.7.2.1.
-
-Upgrading your compiler and libraries
--------------------------------------
-
-Installing libg++ on a Linux system is not as simple as it should be,
-because libg++ shares some basic I/O code with the Linux C library,
-and they must be compatible.  You should get and read the release
-notes for the compiler and libraries.
-
-If you decide to install versions of the libraries that are older (or
-newer) than the ones you already have, you should follow the
-directions in the release notes carefully.
