Memo on building libssh in Windows with MinGW-builds(MinGW-w64)

Requirements: zlib, openssl

Remarks

• zlib: Just mingw32-make -f win32/Makefile.gcc and that’s all
• openssl: Install MSYS from www.mingw.org and use tar on that MSYS package to untar the source tarball. If not, the links on the tarballs are not adequately managed
• libssh: two things
  1. The build directory should be other than the source tree
  2. You’ve got to edit source code to return pthread_self(), rather than pthread_self().p, which is used under #ifdef _WIN32_. This seems to be because of the differences of pthread implementations between mingw.org and mingw-w64 (though not I didn’t compare the source codes)
