qmake makefile/vcproj/vcxproj file generation bug (same for Visual Studio add-in)

My post to forum: http://qt-project.org/forums/viewthread/31252/
For more detail.
For the short description: if any c/cpp/cxx file will contain include with c/cpp/cxx file
For example:
[code]
//some_file_1.c
#include "some_other_file.c"
[/code]
The "some_other_file.c" will be eliminated from Makefile generation or vcproj/vcxproj generation.

I attach to this ticket the test project that show the problem: test_project.zip
(if you build the project the result lib will contain only wfoo() - function, but should contain foo() and wfoo()

And my fixes for qmake utility:
$(QTDIR)/qtbase/qmake/generators/makefile.cpp
$(QTDIR)/qtbase/qmake/generators/makefile.h

that also used for generation vcxproj file for MSVC add-in.
