使用mingw32编译TNN,遇到一点小瑕疵错误，可以修正一下

[sxj731533730]

我使用mingw32 编译器，编译过程中遇到一点小瑕疵错误，因为mingw32仍然需要命名空间支持
[ 99%] Building CXX object CMakeFiles/TNN.dir/source/tnn/utils/split_utils.cc.obj
D:\TNN\source\tnn\utils\split_utils.cc: In static member function 'static tnn::Status tnn::SplitUtils::SplitStr(const char*, tnn::str_arr&, const char*, bool, bool, bool, bool, bool)':
D:\TNN\source\tnn\utils\split_utils.cc:163:23: error: 'min' was not declared in this scope
int len = min((i - cursor), subs_length - 1);

所以我修改为三目运算符，感觉好一点
#if defined(WIN32) && _MSC_VER < 1300 // VC++ 6.0
//int len = min((i - cursor), subs_length - 1);
int len = (i - cursor)>=(subs_length - 1)?(subs_length - 1):(i - cursor);
#else
int len = std::min(i - cursor, subs_length - 1);
#endif

仅建议
