From c4e9570d2e465e774f0e2f6da9526524776a9a8c Mon Sep 17 00:00:00 2001 From: Guilherme Janczak Date: Tue, 11 Jan 2022 16:46:42 +0000 Subject: remove local getopt_long() implementation getopt_long() is widely supported these days, removing it from the source tree should be okay. Here's documentation or the implementation of getopt_long on many systems: All the BSDs: https://man.netbsd.org/NetBSD-9.2-STABLE/getopt_long.3 https://man.openbsd.org/OpenBSD-7.0/getopt_long https://www.freebsd.org/cgi/man.cgi?query=getopt_long https://leaf.dragonflybsd.org/cgi/web-man?command=getopt_long Illumos (OpenSolaris fork): https://illumos.org/man/3c/getopt_long The musl, newlib, and uclibc-ng libcs: https://gogs.waldemar-brodkorb.de/oss/uclibc-ng/src/master/libc/unistd/getopt_long-simple.c#L49-L52 https://git.musl-libc.org/cgit/musl/tree/src/misc/getopt_long.c#n140 https://sourceware.org/git/?p=newlib-cygwin.git;a=blob;f=newlib/libc/stdlib/getopt.c;h=d4f225a7a735dc741d2874eb6c131b6fce2967c5;hb=HEAD#l475 Mingw-w64: https://github.com/mirror/mingw-w64/blob/master/mingw-w64-crt/misc/getopt.c#L542-L549 Mac OS X: https://developer.apple.com/library/archive/documentation/System/Conceptual/ManPages_iPhoneOS/man3/getopt_long.3.html --- src/getopt.h | 130 ----------------------------------------------------------- 1 file changed, 130 deletions(-) delete mode 100644 src/getopt.h (limited to 'src/getopt.h') diff --git a/src/getopt.h b/src/getopt.h deleted file mode 100644 index 0a985b0..0000000 --- a/src/getopt.h +++ /dev/null @@ -1,130 +0,0 @@ -/* Declarations for getopt. - Copyright (C) 1989,90,91,92,93,94,96,97 Free Software Foundation, Inc. - This file is part of the GNU C Library. - - The GNU C Library is free software; you can redistribute it and/or - modify it under the terms of the GNU Library General Public License as - published by the Free Software Foundation; either version 2 of the - License, or (at your option) any later version. - - The GNU C Library is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
