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. ************************************************************************************* */ # endif #endif /* defined _MSC_VER */ #ifdef _WIN32 /* All char* strings are in UTF-8 format.
