anyone has a solution for this gcc compiler error: macro "min" passed 3 arguments but takes just two

This is my code:

template<typename _Tp, typename _Compare>
inline const _Tp&
inline min(const _Tp& __a, const _Tp& __b, _Compare& __comp)
{
   if (__comp(__b, __a))
    return __b ;
  return __a;
}

this is the error message I am getting:

/usr/include/c++/4.4/bits/stl_algobase.h:232:57: error: macro "min" passed 3 arguments, but takes just 2

I understand I am passing 3 arguments a,b and comp but I am only returning a and b, however when I try to return comp it gives me the same message.

You have #define min(a, b) somewhere, so pre-processor try to expand it and failed

Try (min)(a, b, compare). The parentheses around min prevent macro expansion.
