The msgfmt source format specified by POSIX allows multiple plurals and
an arbitrary C expression to select the correct one. So that is one way
to go. The alternative is to stay agnostic to numbers and just always
use all forms in parentheses, e.g. "Loaded %d file(s)".

While I appreciate that the necessity for an expression parser might
increase complexity by a lot, what little I do remember of Russian
suggest that not many simpler alternatives exist. In Russian, just for
example, there are three numbered forms, namely the nominative singular,
the nominative plural, and the genitive plural. The nominative singular
is used whenever the number in question ends in 1 but not 11, the
nominative plural is used for 2-4 but not 12-14, and the genitive plural
is used in all other cases.

That logic is specific to one language (although I suspect a lot might
be shared with other Slavic languages), so it must be specified in the
source format if the feature is desired at all.
