           Summary: Makefiles don't rebuild headers generated from .in
                    files.
           Product: Build scripts
           Version: cvs
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: Makefiles
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: rspencer at x10sys.com


In several situations, the config.status script is run automatically to ensure
that generated files are up to date. For example, if the configure script
changes, the next "make" will force the regeneration and running of the
config.status script to update the generated/configured files.

This is not true of header files such as include/llvm/ADT/hash_map. This file
depends on hash_map.in but if the latter is updated, the next rebuild does not
automatically update hash_map. It could do that by running config.status. 

This bug requests correction of that situation.
