Subject [jira] Created: (STDCXX-269) [gcc/IA64] configuration fails due to -m64 not being recognized

[gcc/IA64] configuration fails due to -m64 not being recognized

                 Key: STDCXX-269
             Project: C++ Standard Library
          Issue Type: Bug
          Components: Configuration
    Affects Versions: 4.1.2, 4.1.3
         Environment: gcc/IA64
            Reporter: Martin Sebor
         Assigned To: Martin Sebor
            Priority: Critical
             Fix For: 4.2

gcc on IA64 doesn't recognize the usual -m64 option. Instead, the -mlpNN option must be used
to select a memory model (from gcc's online help: -milp32|-milp64|-mlp64|-mp64  select data
model (default -mlp64)).
