(I checked this general + approach with Bruno a while back and he said it was fine.) + + However, Gnulib's argp implementation has three bugs which cause this + not to work properly: + + * It hardcodes "libc" as a domain in two places. This is obviously + wrong in Gnulib. + + * It uses argp_domain as both the domain used to translate its own + strings (i.e. string literals in lib/argp-*.c) and the domain used + to translate strings provided by the user, which normally have to + use gettext_noop so that they can be used as 'struct argp_option' + initialisers. This is dreadfully inconvenient because you have to + copy strings about all over the place and keep your POT file up to + date as the argp implementation changes. If argp is in libc then + this is obviously impossible. + + Instead, argp should use DEFAULT_TEXT_DOMAIN to translate its own + string literals (falling back to the default program domain if that + is not set), and should reserve argp_domain for translating strings + that appear in that argp structure. + + * In a number of places, argp uses the domain of the root argp + structure when translating text from a child argp structure. This is + the direct cause of Robert's bug, because the standard --help and + --version options are implemented as a child argp structure with its + own domain. + + My patch changes this to use argp_domain from the child instead. + However, on reflection, I'm not certain that this is correct; + arguably it needs to walk up the tree until it finds a domain to + use. This depends on whether you think that argp_domain == NULL + means "use default program domain" or "use same domain as parent + argp structure". + + https://lists.gnu.org/r/bug-gnulib/2008-03/msg00144.html + +diff --git a/gl/lib/argp-help.c b/gl/lib/argp-help.c +index de98f2143..09a716e69 100644 +--- a/gl/lib/argp-help.c ++++ b/gl/lib/argp-help.c +@@ -48,6 +48,16 @@ + # include "gettext.h" + #endif + ++#ifdef _LIBC ++# define ARGP_TEXT_DOMAIN "libc" ++#else ++# ifdef DEFAULT_TEXT_DOMAIN ++# define ARGP_TEXT_DOMAIN DEFAULT_TEXT_DOMAIN ++# else ++# define ARGP_TEXT_DOMAIN NULL ++# endif ++#endif ++ + #include "argp.h" + #include "argp-fmtstream.h" + #include "argp-namefrob.h" +@@ -144,7 +154,7 @@ validate_uparams (const struct argp_state *state, struct uparams *upptr) + if (*(int *)((char *)upptr + up->uparams_offs) >= upptr->rmargin) + { + __argp_failure (state, 0, 0, +- dgettext (state->root_argp->argp_domain, ++ dgettext (ARGP_TEXT_DOMAIN, + "\ + ARGP_HELP_FMT: %s value is less than or equal to %s"), + "rmargin", up->name); +@@ -220,7 +230,7 @@ fill_in_uparams (const struct argp_state *state) + if (unspec && !un->is_bool) + __argp_failure (state, 0, 0, + dgettext (state == NULL ?
