v1-0001-Use-pg_icu_unicode_version-void-instead-of-pg_icu.patch (text/x-diff)

Hi hackers,

Standard practice in PostgreSQL is to use "foo(void)" instead of "foo()", as the
latter looks like an "old-style" function declaration. 9b05e2ec08a did fix
all the ones reported by -Wstrict-prototypes.

af2d4ca191a4 introduced a new one, this patch fixes it.

Regards,
