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
mingw-pthreads 20110507-1
mingw-runtime 3.20-1
mingw-w32api 3.17-2
