    Subject: [openrisc] gdb problem with const variable types
    Top
    You can get it from CVS:

    cvs -d :pserver:anonymous@cvs.opencores.org:/cvsroot/anonymous login

    When asked for the password, just press return. Now get the GDB source:

    cvs -z9 co or1k/gdb-5.3

    Regards,

    Robert
