- * FIXME: workaround for memory leak in jimtcl 0.80
- * Jim API Jim_CreateCommand() converts the command name in a Jim object and

- * Use the internal jimtcl API Jim_CreateCommandObj, not exported by jim.h,
- * and override the bugged API through preprocessor's macro.
- * This workaround works only when jimtcl is compiled as OpenOCD submodule.
- * It's broken on macOS, so it's currently restricted on Linux only.
- * If jimtcl is linked-in from a precompiled library, either static or dynamic,
- * the symbol Jim_CreateCommandObj is not exported and the build will use the
- * bugged API.
- * To be removed when OpenOCD will switch to jimtcl 0.81
