* Note: OLDMSVCRT, which is defined (in the Makefile) for mingw builds, and
* is not defined for Visual Studio builds.
*
* On Windows XP some those functions are missing from the msvcrt.dll
* When compiled with mingw, the program fails to run due to missing functions.
* One can link to a newer runtime dll, e.g. msvcr100.dll, but that would
* require installing that DLL on the guest. That can be done by downloading
* and installing Microsoft Visual C++ 2010 Redistributable Package.
* (same for 110.dll and 2012 Redistributable Package, etc).
*
* Since we do not want to add this dependency, we use functions that are
* available in msvcrt.dll (and use define in the code).
*
* Currently Visual Studio builds are built with /MT (static mode) such that
* those functions are not required to be in that dll on the guest.
