Yes, that's exactly what will happen. Such applications must be
updated. They must start using strftime("%OB") and nl_langinfo(ALTMON_...).
They must either detect the glibc version at runtime and choose
the correct format specifier or require the minimum glibc version
at build time. I'm willing to contact the upstream developers and
provide the instructions how to change their applications.
I encourage you to review and apply this fix early because other
projects may need to adopt to this change.
And, last but not least, thank you for mentioning cal(1),
this is another application which probably will need to be updated.
Best regards,
Rafal
