declaration of `const AreaSet &CObeyFile::AreaSet () Declaration of "const A &B::A() const" changes meaning of A from "class A"

Hi,

does anyone have an idea, why do I get the following error
(I have to use g++296 on RedHat Linux as compiler):

In file included from r_dir.cpp:9:
r_obey.h:262: declaration of
`const AreaSet &CObeyFile::AreaSet () const'
r_areaset.h:197: changes meaning of `AreaSet' from `class AreaSet'

The afore-mentioned line in r_obey.h is:

class CObeyFile
{
private:
AreaSet iAreaSet;

public:
const AreaSet& AreaSet() const; // line 262

And the line in r_areaset.h is:

class AreaSet
{ // line 197
public:
AreaSet();
~AreaSet();

Same code compiles fine with MS VC++.

Thank you for any hints!
Alex

Well, in r_areaset.h, 'AreaSet' is a class. Then, in r_obey.h, you try
to redeclare it as a function. You can't do that. The easy solution
is to rename the function to something like GetAreaSet().

Your function is called AreaSet, just the same as the class.

but it is a member function (of the class CObeyFile) isn't it?
I still don't understand, why their names clash
