Thanks, Pedro. I just pushed the patch.

Absolutely. Attached is the patch that I just pushed reinstating
them.

        * contrib/ari/gdb_ari.sh: Reinstate checks for "true" and "false".

Subject: [PATCH] Revert "Remove true and false ARI checks now that we use
 stdbool.h."

As we cannot use type bool until conversion to C++ is official,
this patch re-instates the ARI checks for "true/false".

gdb/ChangeLog:

        * contrib/ari/gdb_ari.sh: Reinstate checks for "true" and "false".
