           Summary: Fail to build gcc 4.6.0 (r168594) on mingw32
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: plugins
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: cool...@qq.com


configured with '--disable-shared'
so lto-plugin built as static library
when configuring target libgcc
failed with 'liblto_plugin-0.dll not found' error

I think there is something wrong with the option checking in gcc/gcc.c (line
6812)
LTOPLUGINSONAME is invalid when configured with '--disable-shared'
because there is no dynamic library
