This reverts commit 72b349dd8c209d7375d4d4f76e2315943d654ee9. This removal caused inconveniences to some programmers. We've agreed to keep the information about C89, since there's an easy way to keep it correct by checking against a plain-text copy of the standard itself: $ stdc89() { grep "[[:alpha:]] \**\b$1([[:alnum:]*,. ]*);" /path/to/c89-draft.txt; } $ stdc89 printf int printf(const char *format, ...); int printf(const char *format, ...); We will also do a split of the information in STANDARDS, since now it's a mix of what a proper STANDARDS section would be plus a HISTORY section commonly-found in other manual pages. C89 will go into HISTORY.
