We currently have macros silently replacing use of strncpy/strcat with strcpy_s/strcat_s when using MSVC++. However, these macros can have unexpected effects as they use sizeof to find out the maximum size of the destination string. This is a very significant difference from strncpy/strcat, which can lead to subtle bugs as the behaviour is different between mingw and MSVC++. Now that we have our implementation of strcpy_s/strcat_s, we don't need these #defines.

* Note: OLDMSVCRT, which is defined (in the Makefile) for mingw builds, and

|
|
* 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.
