           Summary: Fix compiler warnings about unused 'rc' variables.
           Product: eCos
           Version: CVS
          Platform: All
        OS/Version: Other
            Status: NEW
          Severity: enhancement
          Priority: low
         Component: C library
        AssignedTo: unassigned@bugs.ecos.sourceware.org
        ReportedBy: grant.b.edwards@gmail.com
                CC: ecos-bugs@ecos.sourceware.org
             Class: Advice Request


In abort() and exit() the 'rc' variable is set but unrefernced unless
either asserts or tracing is enabled.  This patch marks those 'rc'
variables with the CYGBLD_ATTRIB_UNUSED attribute so the compiler
won't warn us about them being set but unreferenced.

No patch attached, but if it matches your description, that's trivial and, so,
fine - please check it in.
