Unexpected use of Q_WGL in ~QGLWidget

Hi,

I found this while investigating a completely different issue in our Windows application, but thought I'd raise it with you.

Looking at the destructor for QGLWidget in src/opengl/qgl.cpp, in Qt4.6.3, I noticed the code:

#if defined(Q_WGL)
delete d->olcx;
#endif

However, all the other references to the member variable olcx that I can see are predicated on the #define Q_WS_WIN.

I don't see any other reference to Q_WGL in any source or associated files in Qt4.6.3.

Should that statement be compiled into Windows builds?

Thanks!

Mark
