I am compiling a C program on CentOS 6.8 and I see a lot of syntax errors in gcc include header files at token '???', but it can generate the binary eventually.
The cproto version I am using is 4.6 and I have tried gcc 4.4.7 and gcc 5.4. I am confused what went wrong with my /usr/include/*.h. Any help would be really appreciated.
Here is part of the log:
