I am tying to existing c++ code (compilable with gcc version 4.3.4) with gcc version 10 but getting error. below is the compilation command and error.

g++ -m32 -pipe -g -MD -O3 -mcpu=pentium4 -mfpmath=sse -msse2 -Dlint -DLinux -D_REENTRANT - DOS_LINUX_2_2 -DOS_USE_ALTERNATE_STD -DOS_NO_WSTRING -DOS_MULTI_THREADED -DOS_LINUX_PTHREADS -DOS_PTHREADS -DOS_REALTIME -D_REENTRANT -DCC_DEBUG=0  -DNDEBUG -I. -I/{PATHS}  -c source.cpp -o obj/source.o

g++: warning: ‘-mcpu=’ is deprecated; use ‘-mtune=’ or ‘-march=’ instead

there are many other errors also. When I try to run a sample program with this header included it compiled successfully.

    #include<bits/cpp_type_traits.h>
    #include<iostream>
    int main()
    {
        std::cerr<<"Hello";
        return 0;
    }

What could be the issue?
