Update.
2000-08-20 Ulrich Drepper <drepper@redhat.com> * intl/loadmsgcat.c (_nl_unload_domain): Also free conv_tab element. Pretty printing. * intl/plural.y (new_exp): Take number of optional parameters in second parameter. Test for correct number of parameters and free correctly in case of failure. Adjust all callers. (yylex): Allow ';' as terminator character.
