The bourn shell script ``gdb-events.sh'' creates the files
``new-gdb-events.c'' and ``new-gdb-events.h and then compares
them against the existing ``gdb-events.[hc]''. Any differences
found being reported.
If editing this file, please also run gdb-events.sh and merge any
changes into that script. Conversely, when making sweeping changes
to this file, modifying gdb-events.sh and using its output may
prove easier. */
