Subject: [PATCH] Issue #173, follow up to using strtoll to allow this to work
 on older Windows environments: Use cmake to generate config.h from
 config.h.win32, including checking for strtoll with cmake, or fall back to
 _strtoi64 for older MSVC's. Also, add a few missing files to the list of
 sources to build.
