  "message": "sim: Check known getopt definition existence\n\nClang generates a warning if there is a function declaration/definition\nwith zero arguments.  Such declarations/definitions without a prototype (an\nargument list) are deprecated forms of indefinite arguments\n(\"-Wdeprecated-non-prototype\").  On the default configuration, it causes a\nbuild failure (unless \"--disable-werror\" is specified).\n\ninclude/getopt.h defines some getopt function definitions but one of them\nhas a form \"extern int getopt ();\".  If this form is selected in\ninclude/getopt.h, Clang generates a warning and the build fails by default.\n\nIn really old environments, this getopt definition with no arguments is\nnecessary (because the definition may change between environments).\nHowever, this definition is now a cause of problems on modern environments.\n\nA good news is, this definition is not always selected (e.g. if used by\nbinutils/*.c).  This is because configuration scripts of binutils, gas,\ngprof and ld tries to find known definition of getopt function is used and\ndefines HAVE_DECL_GETOPT macro.  If this macro is defined when getopt.h is\nincluded, a good form of getopt is used and Clang won\u0027t generate warnings.\n\nThis commit adds a modified portion of ld/configure.ac to find the known\ngetopt definition.  If we could find one (and we *will* in most modern\nenvironments), we don\u0027t need to rely on the deprecated definition.\n",
