Readline: Cleanup some warnings
Cleanup the readline warnings that gdb buildbot complains about.
To prevent wcwidth missing declaration warnings, add the SOURCE /
EXTENSION macros to config.in that have already checked for in
configure.
Ensure pid is a long before printing as one. Also fix GNU style.
Check the return value of write the same way as history_do_write ().
These changes are consistent with upstream readline.
readline/ChangeLog.gdb:
* config.h.in: Add SOURCE/EXTENSION macros.
* histfile.c (history_truncate_file): Check return of write.
* util.c (_rl_tropen): Ensure pid is long.
