539 | dnl If TOOLSYMBOL is specified and is 'use-libtool', then a libtool library | |
540 | dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static, | |
541 | dnl depending on --{enable,disable}-{shared,static} and on the presence of | |
542 | dnl AM-DISABLE-SHARED). Otherwise, a static library | |
543 | dnl $(top_builddir)/intl/libintl.a will be created. | |
544 | dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext | |
545 | dnl implementations (in libc or libintl) without the ngettext() function | |
546 | dnl will be ignored. | |
547 | dnl LIBDIR is used to find the intl libraries. If empty, | |
548 | dnl the value `$(top_builddir)/intl/' is used. | |
549 | dnl | |
550 | dnl The result of the configuration is one of three cases: | |
551 | dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled | |
552 | dnl and used. | |
553 | dnl Catalog format: GNU --> install in $(datadir) | |

556 | dnl Catalog format: GNU --> install in $(datadir) | |
557 | dnl Catalog extension: .mo after installation, .gmo in source tree | |
558 | dnl 3) No internationalization, always use English msgid. | |
559 | dnl Catalog format: none | |
560 | dnl Catalog extension: none | |
561 | dnl The use of .gmo is historical (it was needed to avoid overwriting the | |
