             Bug #: 56754
           Summary: some missing plugin headers during installation in gcc
                    4.8
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: plugins
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: pageexec@freemail.hu


it used to be the case before 4.8 that the following files were made available
to plugins:

 target.h
 target.def
 target-hooks-macros.h

now it seems that at least for a x86_64-pc-linux-gnu target they no longer get
installed. i tried to find the related commit but came up empty so i'm
wondering if this is the result of an oversight or some policy change? manually
installing these files gets things back to normal, but it'd be nice to know
what to expect in the future or if it's a bug, fix it for 4.8.1 ;).
