Saturating to ULONG_MAX is not correct for languages where the plural form depends on n%10 or n%100 (see the various Plural-Forms entries in the .po files). If n is too large you want something like n % 1000000 + 1000000 instead to get the correct plural form in all cases. -- Joseph S. Myers jos...@codesourcery.com
