[Boost-users] Intel Compiler: "warning #1170: invalid redeclaration of nested class" with bimaps

Dear Experts.

I am getting "invalid redeclaration of nested class" warnings when I
include "bimap/bimap.hpp" and use intel compiler(v12).  Actually,
these warnings are still present when the source has nothing but the
#include and an empty main().

I noticed that I don't get these warnings with gcc (v4.1.2).

I tried to debug the warning but I am still not sure whether the
compiler (and/or boost settings for it) is beeing extra carefull and
the warning is benign.

Thank you,
Oleksiy
