Problem in types.h

I am trying to compile a C++ code I am doing for my university, using g++. However, I see two problems that I just can`t find out the reason. The first one is "empty character constant", pointing to a line where I define 3 pointers to char.

The second and most incredible one is: "/usr/include/sys/types.h:84: error: expected ';' before 'typedef'"...

I've never done anything in this types.h file... And I`ve never had problems compiling other codes...

Does anyone has any idea of how to fix these mistakes????

Show us the line of code with the 3 pointers and char.

Line 84 in types.h is:

#if !defined(_POSIX_C_SOURCE) || defined(_DARWIN_C_SOURCE)
typedef unsigned char u_char;

Click to expand...

Thanks...
I've already fixed the first problem, with the char declaration. Now I only have to fix the types.h problem. I've checked in my types.h file, and it looks just like yours...

I can't find out why this problem is happening...
