Macro redefinition warning of "UINT_MAX"

[danielecesarini]

In "msr_rapl.h" there is the macro definition:

#define UINT_MAX 4294967295U

The macro definition is taken from "limits.h" (as the comment say) but if I need to use "limits.h" (or a library which include "limits.h", as instance HWLOC library) this macro consequently raises a warning because the compiler discover a macro redefinition.

Thanks @danielecesarini! I haven't had a chance to test this, but if we were to remove the UINT_MAX macro and instead include limits.h, would this resolve the issue?

Yes, it works.
