Re: [Boost-users] Serialization triggers .lib and .exp file generationin VS2005

This is a side effect of the steps taken inhibit the compiler from
eliminationg code not explicitly referred to. (aka code stripping).

Just ignore the *.exp and *.lib files.  I 'm surprised that they
take a lot of time to generate but I don't know how to
avoid it and have the serialization library still work as
advertised.
