enblend solution build fails

[hbl]

Building the latest enblend_msvc2008, fails in enfuse at the following
line:

class NotifyingDirectionSelector<UnstridedArrayTag, T, Notify>
{
friend class Notify::self_type; //error C2242


Is anyone else getting this error?

I can confirm this error on Win32, MSVC 9.0.
It seems to be a problem of friendship specification between classes.
The MSVC compiler needs to know the class. Unfortunately I'm not
familiar with the code or the template class specifications.
Maybe Andrew Mihal can clearify the case, because he introduced the
changes in the latest CVS revision, which yields to the failed build on
MSVC.

Thanks for the reply, Guido. I am trying to sort through it but it is
tough going not being familiar with the code. I put in a support
request on the project tracker. Hopefully Andrew will step in with a
solution.

Hi,

Using 'typename' instead of 'class' should fix the problem. Ie.

friend typename Notify::self_type;

Dear Fahim,

Thank you for this hint. After small modification as suggested the build
processed finished successfully.

Confirm here on MSVC 8 EE - works like a charm. Patch attached. Thanks
Fahim!

Confirm successful build using Visual C++ 2008 Express Edition.
