           Summary: Sparc CBE generates bad declaration of write() system
                    call
           Product: libraries
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: C backend
        AssignedTo: criswell at uiuc.edu
        ReportedBy: criswell at uiuc.edu


The Sparc C Backend generates an extern declaration of the write() system call
for the unwind instruction.  This declaration omits the return type, so it
defaults to int.

This breaks code which declares write() on SparcV9 because write() returns a 64
bit value.  The types don't match and GCC refuses to compile the code if there
are too many warnings.
