* getopt: annotate files with relationship to gnulib.Zack Weinberg2017-04-071-1/+2
| | | | | | | | | | | | | | As the final act in this patchset, adjust the "This file is part of the GNU C Library" message at the top of each file to indicate which files are synced with gnulib. * posix/bits/getopt_core.h, posix/bits/getopt_ext.h * posix/getopt.c, posix/getopt1.c, posix/getopt_int.h: Mention in top-of-file boilerplate that these files are shared with gnulib. * posix/getopt.h, posix/bits/getopt_posix.h: Mention in top-of-file boilerplate that these files are NOT shared with gnulib, unlike the rest of the getopt implementation.
* getopt: eliminate __need_getopt by splitting up getopt.h.Zack Weinberg2017-04-071-0/+76
__need_getopt is misnamed; what it really means is "we want only the getopt features specified in POSIX, not the GNU extensions". Because this code is shared with gnulib, it winds up being cleanest to split getopt.h into *four* headers. getopt_core.h and getopt_ext.h will be shared with gnulib, getopt_posix.h will be just for glibc, and each project will have its own copy of getopt.h. * posix/bits/getopt_core.h, posix/bits/getopt_ext.h: New files, intended to be shared with gnulib. * posix/bits/getopt_posix.h: New file, not intended to be shared with gnulib. * posix/getopt.h: Now just includes features.h, bits/getopt_core.h, and bits/getopt_ext.h. Will no longer be shared with gnulib. * include/bits/getopt_core.h, include/bits/getopt_ext.h * include/bits/getopt_posix.h: New wrappers. * posix/Makefile: Install new headers. * posix/unistd.h, libio/stdio.h: Include bits/getopt_posix.h instead of getopt.h.
