+GiNaC.  When using GCC3 as compiler please use at least CLN-1.1.1
+since some parts of GiNaC won't build with CLN-1.1.
+
+Problems with building ginsh
+----------------------------
+
+The most common reason why this doesn't succeed is the absence of
+libreadline and/or the corresponding header files.  Depending on what
+your system/distribution is, you will have to install a package called
+libreadline and maybe libreadline-dev.  If your system's vendor
+doesn't supply such packages, go to <ftp://ftp.gnu.org/gnu/readline/>
+and compile it yourself.
+
+Problems with missing standard header files
+-------------------------------------------
+
+Building GiNaC requires many standard header files.  If you get a
+configure error complaining about such missing files your compiler and
+library are probably not up to date enough and it's no worth
+continuing.  If the only file missing is <sstream>, however, there is
+a solution.  GCC-2.95.2 and earlier don't ship with this file.  A
+working implementation has been available since GCC-2.95.3.  GCC-3.0
+and later have an even better, fully standard-conforming
+implementation, by default.  If you are stuck with GCC-2.95.2 or
+earlier and you cannot upgrade your compiler we recommend obtaining
+the libstdc++-v2 <sstream> header written by Magnus Fromreide.  It was
