buildbot MSVCWinr 62566 failed, seems to try to compile an header file: \win32ss\user\winsrv\consrv\consrv.h

Was looking why buildbot failed:

ninja: build stopped: subcommand failed.
Exiting, ISO not built"

For me it looks like ninja try to compile consrv.h, an header file.... which seems wrong to me.
