Passing appropriate -static-* options to g++ solves it for me, though 
strangely enough I can't find the corresponding .a files either:

$ cat scratch.cpp
#include <string>
#include <iostream>
int main() {
     std::string s = "hi";
     std::cout << s << std::endl;
}

$ i686-pc-mingw32-g++ scratch.cpp && cygcheck ./a >/dev/null && ./a
cygcheck: track_down: could not find libgcc_s_dw2-1.dll
cygcheck: track_down: could not find libstdc++-6.dll

$ i686-pc-mingw32-g++ -static-libgcc -static-libstdc++ scratch.cpp && 
cygcheck ./a >/dev/null && ./a
hi

$ cygcheck -dc | grep mingw
mingw-binutils                 2.21-1
mingw-gcc-core                 4.5.2-1
mingw-gcc-g++                  4.5.2-1
