* configure.ac (GPGRT_ENABLE_ARGPARSE_MACROS): Define. * common/argparse.c, common/argparse.h: Rewrite. * tests/gpgscm/main.c: Switch to the new option parser. * g10/gpg.c: Switch to the new option parser and enable a global conf file. * g10/gpgv.c: Ditto. * agent/gpg-agent.c: Ditto. * agent/preset-passphrase.c: Ditto. * agent/protect-tool.c: Ditto. * scd/scdaemon.c: Ditto. * dirmngr/dirmngr.c: Ditto. * dirmngr/dirmngr_ldap.c: Ditto * dirmngr/dirmngr-client.c: Ditto. * kbx/kbxutil.c: Ditto. * tools/gpg-card.c: Ditto. * tools/gpg-check-pattern.c: Ditto. * tools/gpg-connect-agent.c: Ditto. * tools/gpg-pair-tool.c: Ditto. * tools/gpg-wks-client.c: Ditto. * tools/gpg-wks-server.c: Ditto. * tools/gpgconf.c: Ditto. * tools/gpgsplit.c: Ditto. * tools/gpgtar.c: Ditto. * g13/g13.c: Ditto. * g13/g13-syshelp.c: Ditto. Do not force verbose mode. * sm/gpgsm.c: Ditto. Add option --no-options. -- This is backport from master commitcdbe10b762commitba463128cecommit3bc004decdcommit2c823bd878commit0e8f6e2aa9but without changing all functions names to gpgrt. Instead we use wrapper functions which, when building against old Libgpg-error versions, are implemented in argparse.c using code from the current libgpg-error. This allows to keep the dependency requirement at libgpg-error 1.27 to support older distributions. Tested builds against 1.27 and 1.40-beta. Note that g13-syshelp does not anymore default to --verbose because that can now be enabled in /etc/gnupg/g13-syshelp.conf. GnuPG-bug-id: 4788 Signed-off-by: Werner Koch <wk@gnupg.org>
