[bug-gettext] Problem with mixing plural and simgle form

[Marian Cavojsky]

Hi.

I have a problem with translations where are mixing single and plural forms.

I have test program in c:
$ cat testgettext.c
// Test bug in gettext mixing plural and single form

#include <libintl.h>
#include <locale.h>
#include <stdio.h>
#include <stdlib.h>
int main(void)
{
  setlocale( LC_ALL, "" );
  bindtextdomain( "testgettext", "/usr/share/locale" );
  textdomain( "testgettext" );
  printf( gettext( "Hello, world!\n" ) );
  printf( ngettext( "Hello, world!\n", "Hello, worlds!\n", 2) );
  exit(0);
}
$ ----------------------------------

$ xgettext -d testgettext -s -o testgettext.pot testgettext.c
$ msginit -l sk -o testgettext.po -i testgettext.pot

with modified po file for slovak language:

$ cat testgettext.po

msgstr[1] "1 - Ahoj, svet!\n"
msgstr[2] "2 - Ahoj, svety!\n"
$ ----------------------------------

$ msgfmt -c -v -o testgettext.mo testgettext.po
1 preložená správa.
$ sudo cp testgettext.mo /usr/share/locale/sk/LC_MESSAGES/testgettext.mo 
$ ./testgettext 
0 - Ahoj, svety!
2 - Ahoj, svety!

For single form (line 12) translation code used message with index "0" and not
"1" which is written in plural-forms formula.

Correct output:
$ ./testgettext 
1 - Ahoj, svet!
2 - Ahoj, svety!

Either do not mix single form msgid with messages for plural forms, or really
use the plural-forms formula for single form messages.

My version of gettext:
$ equery l gettext
 * Searching for gettext ...
[IP-] [  ] sys-devel/gettext-0.18.1.1-r1:0
$ gettext --version
gettext (GNU gettext-runtime) 0.18.1

Please send the answer to my e-mail address. I am not in mailing-list.
