And just to be paranoid, I checked a few more things: the .mo
definitely contains the literal "PRId64"  (rearranged as
"^@PRId64^@the answer is %") and it's definitely using gettext() from
libc and not somehow automatically finding a GNU library in some
search path.  (And woop, this cfarm Sun box has received the new
preadv()/pwritev() in its libc, that they added for PostgreSQL.)

And since I remembered that I had a NetBSD vagrant VM handy from
investigating Champion's libpq troubles the other day:

[vagrant@netbsd9 gettext-hacking]$ cc test.c -lintl
[vagrant@netbsd9 gettext-hacking]$ ldd a.out
a.out:
        -lintl.1 => /usr/lib/libintl.so.1
        -lc.12 => /usr/lib/libc.so.12
[vagrant@netbsd9 gettext-hacking]$ ./a.out
la réponse est 42

Not that I had much doubt but I checked that the library is indeed the
NetBSD code and not somehow GNU code, based on clearly identifiable
strings.
