2000-01-21 Ulrich Drepper <drepper@cygnus.com> * intl/Makefile (routines): Add dcigettext, dcngettext, dngettxt, ngettext, and plural. (distribute): Add plural.y, po2test.sed, and tst-gettext.sh. (test-srcs): Add tst-gettext. (before-compile): Add $(objpfx)msgs.h. Add rules for plural.c and msgs.h generation and running tst-gettext.\ * intl/Versions [GLIBC_2.2]: Add __dcngettext, dcngettext, dngettext, and ngettext. * intl/dcgettext.c: Move most code into dcigettext.c. Add call dcigettext with appropriate parameters. * intl/dcigettext.c: New file. * intl/dcngettext.c: New file. * intl/dngettext.c: New file. * intl/ngettext.c: New file. * intl/gettextP.h (struct expression): Define. (struct loaded_domain): Add plural and nplurals members. Add prototypes for new internal functions. * intl/libintl.h: Declare new functions. Add optimizations for them. * intl/loadinfo.h: Add new parameter to _nl_find_msg declaration. * intl/loadmsgcat.c (_nl_load_domain): Search for plural information in header entry and parse and store the expression. * intl/plural.y: New file. * intl/po2test.sed: New file. * intl/tst-gettext.c: New file. * intl/tst-gettext.sh: New file. * intl/gettext.c: Call __dcgettext directly.
