Follow eg the Rcpp Gallery story and use

    Sys.setenv("PKG_LIBS"="C:\MinGW\lib\libboost_regex.a")

as static library can be given "as is".  Else try 

    Sys.setenv("PKG_LIBS"="-LC:\MinGW\lib\ -lboost_regex")

which is the standard form.  That should work with the example I posted.

If everthing else, try the documentation for Rcpp (Rcpp-package vignette in
particular) or Boost.
