It seems that a reference to {{{std::wstring}}} is not protected by the appropriate boost feature flag.

bjam was generated in the follwing way:
{{{
$ ./bootstrap.sh --prefix=$HOME/local --exec-prefix=$HOME/local/${MACHTYPE=i686-pc-cygwin}
}}}

It is compiled on Windows XP machine, under a recent update of Cygwin.

Attached {{{svn diff}}} seems to solve the compilation errors.
