             Bug #: 56410
           Summary: [4.8 Regression] bootstrap with ada on
                    x86_64-w64-mingw32 fails in gnattools, new dependency
                    on gmp.h
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: ada
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: rainer@emrich-ebersheim.de
              Host: x86_64-w64-mingw32
            Target: x86_64-w64-mingw32
             Build: x86_64-w64-mingw32


A commit between revision 194638 and 195218 introduced a new dependency on
gmp.h, which is not found because the required include search path isn't added.

So, if the dependency is by intention, the include search path has to be added.
Otherwise the dependeny has to be removed again.
