Submitting it to me was fine. I CC bug-gnulib, because that's the primary
forum for discussing portability code like this one.

Specifying -m64 in the CFLAGS is not enough. The autoconf documentation [1]
recommends to use either

The reason is precisely so that autoconf tests which run the preprocessor
will yield the expected result.
