            Bug ID: 66884
           Summary: trunk/boehm-gc/cord/cordbscs.c:455: bad if ?
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: boehm-gc
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dcb314 at hotmail dot com
  Target Milestone: ---

[trunk/boehm-gc/cord/cordbscs.c:455]: (style) Checking if unsigned variable 'i'
is less than zero.

#   ifndef __STDC__
      if (i < 0) ABORT("CORD_substr: second arg. negative");
        /* Possible only if both client and C implementation are buggy. */
        /* But empirically this happens frequently.         */
#   endif

but

CORD CORD_substr(CORD x, size_t i, size_t n)

Suggest code removal. It seems to be dead, and I don't think anyone
still uses K&R (ie pre ANSI) compilers anymore.
