Windows .res files do not get recompiled, if included files change

I have an .rc file containing some Windows specific resources for my application.
It is included in the project file "RC_FILE += resources.rc"
This resource file includes another file, called revision.inc, which is being generated automatically and includes the SVN revision number, etc.

When the included revision.inc file changes, the resources.rc should recompile to produce an up to date .res file
But the .res file does not regenerate.
Native Visual Studio projects handle files included into resource scripts correctly.

When you check the Makefile generated by QMake. The .res file only depends on the .rc file. Any files included into the .rc file are ignored.
