These security functions are available when building with MSVC++. With mingw, they can be used at build time, but their availability will depend on the version of MSVCRT the user has installed on their system. In particular, a default install of Windows XP will not have a new enough MSVCRT version, causing runtime failures as the binary built with mingw and using strcat_s will not be able to find the necessary entry point in the MSVCRT runtime. This commit adds some strcat_s/strcpy_s-like functions used with mingw which will always be available.
