+As of Date=2011-02-27:
 
+  There's two compilers, that I(Larry Evans) know of that can compiler
+  variadic templates.  The first is gcc.  Recently (2011 Jan), clang
+  has been able to compile variadic templates; however, it still has
+  some problems, unrelated to variadic templates, on linux:
+  
+    http://lists.cs.uiuc.edu/pipermail/cfe-dev/2011-February/013533.html
+    
+  For g++, only later versions (>= g++4.5) will work:
+  
+    The tests in libs/composite_storage/sandbox/pack were compiled and
+    run with:
+     
+    ftp://gcc.gnu.org/pub/gcc/snapshots/4.5-20100408/gcc-g++-4.5-20100408.tar.bz2
+    
+    An earlier version:
+    
+    ftp://gcc.gnu.org/pub/gcc/snapshots/4.4-20090630/gcc-4.4-20090630.tar.bz2
+    
+    failed to compile one test and gave error message:
+    
+    one_of_multiple_dispatch.test.cpp:371: instantiated from here
+    ../../../../boost/composite_storage/pack/multiple_dispatch/replace_source_with_target_ptr.hpp:84:
+    error: incompatible types in assignment of '<brace-enclosed
+    initializer list>' to 'void* [2]'
+    
+  In addition, the compiler needs to be called with the:
+  
+   -DBOOST_MPL_CFG_NO_PREPROCESSED_HEADERS
+   
+  option.  This is because, otherwise, compilation of files such as:
+  
+    http://svn.boost.org/svn/boost/sandbox/variadic_templates/libs/composite_storage/sandbox/pack/predator_prey.cpp
+    
+  will result in errors, such as:
