-You will also need a decent ANSI-compliant C++-compiler. We recommend
-the C++ compiler from the GNU compiler collection, GCC >= 3.0. If you
-have a different or older compiler you are on your own. Note that you
-may have to use the same compiler you compiled CLN with because of
-differing name-mangling schemes.

+(it can be downloaded from http://www.stack.nl/~dimitri/doxygen) and

+Known to work with:
+ - Linux on x86 and x86_64 using
+ - GCC 3.4, 4.0, 4.1, 4.2, 4.3.x (x >= 1), 4.4, 4.5, and 4.6
+ - Clang 2.8
+ - Windows on x86 using GCC 3.4 (MinGW)
+
+Known not to work with:
+ - Clang 2.7 and earlier due to poor C++ support.
+ - GCC 4.3.0 due to the compiler bug,
+ see <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35548>.
+ - GCC 2.96 or earlier because proper exception and standard library support
+ is missing there.
+
+If you install from git, you also need GNU autoconf (>=2.59), automake (>=1.8),
+libtool (>= 1.5), bison (>= 2.3), flex (>= 2.5.33) to be installed.
