win10，MinGW14.2编译。

最近升级了编译器，发现用新的编译器编译EasyX程序不通过

编译指令：

-O2
-std=c++11
-I"C:\mingw64\include"
-I"C:\mingw64\x86_64-w64-mingw32\include"
-I"C:\mingw64\lib\gcc\x86_64-w64-mingw32\14.2.0\include"
-I"C:\mingw64\lib\gcc\x86_64-w64-mingw32\14.2.0\include\c++"
-L"C:\mingw64\lib"
-L"C:\mingw64\x86_64-w64-mingw32\lib"
-static-libgcc

错误：
