But now I see it's in the "header" that's, by convention, the translation for "".

You could cache results. Or (this is likely the more reasonable implementation) just hard-code the expression strings that are actually used for real languages and implement them in C when a match is found. > Plural-Forms: nplurals=2; plural=n == 1 ? 0 : 1; > > The nplurals value must be a decimal number which specifies how many > different plural forms exist for this language.

This is a very poor description. Does it allow casts? Compound literals? Floating point? Function calls? ...? Rich
