/*
*************************************************************************************
* V110_SDK71, in MSVC 2017 also known as v141_xp, is a platform toolset that is supposed
* to target Windows XP. It turns out however that certain functions provided silently fail
* on Windows XP only, which makes debugging challenging. This only occurs when building with
* /MT. This problem has been reported to Microsoft, but there hasn't been a fix for years. See
* https://web.archive.org/web/20170327195018/https://connect.microsoft.com/VisualStudio/feedback/details/1557168/wstat64-returns-1-on-xp-always
*
* It is known that this problem affects the functions _wstat64 (used by flac_stat i.e.
* stat64_utf8) and _fstat64 (i.e. flac_fstat) and therefore affects both libFLAC in
* several places as well as the flac and metaflac command line tools
*
* As the extent of this problem is unknown and Microsoft seems unwilling to fix it,
* users of libFLAC building with Visual Studio are encouraged to not use the /MT compile
* switch when explicitly targeting Windows XP. When use of /MT is deemed necessary with
* this toolset, be sure to check whether your application works properly on Windows XP.
* It is also possible to build for Windows XP with MinGW instead.
