- Updated to use StackWalk64 function call, requiring some addition of headers from MinGW-w64 to compile with MinGW.
- Code added to support 64-bit executables: functionality added and one warning fixed.
- New DLL binaries compiled using i686-MinGW-w64 and x86_64-MinGW-w64. (Oddly, the DLL built with MinGW is 5 MB while MinGW-w64's is 1 MB.)
