Hello, dear developes

Some times ago I have started porting some system to wine and was disappointed that application hangs.  So I have began use dbghelp.
I have faced with problem in supporting dpb files in wine which was generated by Visual Studio 2012. I have found an article: http://bugs.winehq.org/show_bug.cgi?id=835 where Dan Kegel public a series of fixes.
But support was for VS2008 and post was dated by 2009-11-01. So may be this fix already included in Wine1.6 and debug symbols cant recognized by dbghelp due of another problem?
Can anybody explain this?
