Since ksh 93u+m comes bundled with libast 20111111, there's no need to support older versions, so this is another cleanup opportunity. src/cmd/ksh93/include/defs.h: - Throw an #error if AST_VERSION is undefined or < 20111111. (Note that _AST_VERSION is the same as AST_VERSION, but the latter is newer and preferred; see src/lib/libast/features/api) All other changed files: - Remove legacy code for versions older than the currently used versions, which are: _AST_VERSION 20111111 ERROR_VERSION 20100309 GLOB_VERSION 20060717 OPT_VERSION 20070319 SFIO_VERSION 20090915 VMALLOC_VERSION 20110808
