+'''Boost 1.46.1 libraries on a Fedora 7 Linux''' 
+
+[http://lists.boost.org/Archives/boost/2011/03/179178.php]
+
+Boost 1.46.1 libraries on a Fedora 7 Linux system with the default g++ 4.1.2.
+
+The warnings from the math library produce zillions of lines of output.  Each warning has a long description of the instantiation and then concludes with a couple of 
+lines like this:
+
+{{{
+./boost/math/special_functions/binomial.hpp:65:   instantiated from here
+./boost/mpl/assert.hpp:79: warning: lowering visibility of 'int 
+mpl_::assertion_failed(typename mpl_::assert<C>::type) [with bool C = 
+false]' to match its type
+}}}
+
+The workaround for this is to add
+
+ cxxflags=-Wno-attributes
+
+to the <compileflags> and <linkflags> in user-config file
+
+Fixed by Redhat for g++ 4.5.1 on Fedora 14
