The circa-1996 runtime tests to catch potential Y2K problems are no longer worth the maintenance hassle, as the Y2K transition was done many years ago. * Makefile, NEWS: Mention this. * strftime.c (YEAR_2000_NAME, IN_NONE, IN_SOME, IN_THIS, IN_ALL): Remove. All uses removed. (strftime): Do not warn about Y2K problems. (_fmt): Omit last (warning) arg; all uses changed.
Please reconsider removing this, and change it if necessary to DEPRECATE_TWO_DIGIT_YEARS, as the lessons have not been learned, and that nasty habit has persisted and spread, with more programs generating two digit years and months and days, resulting in confusion on ~.4 of the dates in each year, and ~.666 of the last 18 years, unless you happen to know the project's rules or program's locale (if they even support locales) with certainty. Personally I would like to see any use of %y dropped, declared UB, or at least unspecified behaviour, with the options of treating it as %Y, or deletion of the source file containing it, unless suppressed by a directive such as #pragma BONEHEAD_SINCE_EPOCH, when it should have been deprecated! -- Take care.
