Title: Fixed linker error for MSVC2010.

In MSVC2010 std::string::npos is not exported from std libs but
since it's a constant value it's safe to declare this in the header
file so every lib that's using it has a local instance.

This is actually a workaround specific for MSVC2010, but it seems to make
all code build and operational.
