Thanks for the report.

Often, we'll use a prefix. In this case, I used "rx_", and renamed
the variable to "rx_sim_is_open".

sim/rx/ChangeLog:

        * gdb-if.c (open): Rename to...
        (rx_sim_is_open): This. Replace all uses of "open" by uses of
        "rx_sim_is_open" throughout.

Tested by rebuilding on x86_64-linux. Pushed on master and gdb-7.9-branch.
