test-intprops.c: many new warnings

[Jim Meyering]

Still trying the latest from gnulib via coreutils,
"make check" was inundated with new warnings.
Nearly 500 lines worth.

Of course, I could simply turn off the warnings and/or -Werror
when building in gnulib-tests/, but I'd rather not.
I'll defer "upgrading to the latest" for now ;-)
