c++ - Visual Studio: project is not up to date "because "AlwaysCreate" was specified"?

Question

I've migrated a solution from VS2008 to VS2010 (SP1).
Now one of my project never finds peace in being up-to-date. Every build have the following output:

1>------ Build started: Project: PROJ_NAME, Configuration: Release Win32 ------
1>Build started 19/05/2011 7:59:27 AM.
1>InitializeBuildStatus:
1>  Creating "ReleasePROJ_NAME.unsuccessfulbuild" because "AlwaysCreate" was specified.
1>ClCompile:
1>  All outputs are up-to-date.
1>  All outputs are up-to-date.
1>Lib:
1>  All outputs are up-to-date.
1>  PROJ_NAME.vcxproj -> C:projFolder.PROJ_NAME.lib
1>FinalizeBuildStatus:
1>  Deleting file "ReleasePROJ_NAME.unsuccessfulbuild".
1>  Touching "ReleasePROJ_NAME.lastbuildstate".
1>
1>Build succeeded.
1>
1>Time Elapsed 00:00:00.09
========== Build: 1 succeeded, 0 failed, 5 up-to-date, 0 skipped ==========

Any ideas?

Answer 1

I had a similar problem when one of the include files listed in the project didn't actually exist. I had deleted the file, but forgot to remove it from the project.

The dependency checker then believes the project is not up to date, but the builder finds nothing to build.
