           Summary: libstdc++ basic_file.cc compile fails with ioctl
                    redeclaration
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: target
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: rbrown64 at csc dot com dot au
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: i686-unknown-sysv5UnixWare7.1.0
  GCC host triplet: i686-unknown-sysv5UnixWare7.1.0
GCC target triplet: i686-unknown-sysv5UnixWare7.1.0

The change to fix PR bootstrap/11272 on -06-21, including <unistd.h>
causes the compile of basic_file.cc to fail.
sys/sockio.h included from sys/ioctl.h declares a static ioctl causing the
error below. Should fixinclude sys/sockio.h to #define ioctl to avoid the
redeclaration - does both sys/sockio.h and unistd.h need fixing to be order
independant.
