And of course I'm completely retarded here, since sizeof (foo) will
never expand to a numeric constant for the preprocessor. Anyhoo...

Going with SIZEOF_OFF_T. The configure script automatically detects the
right value for this, but of course that's not going to help you. I
suppose you could either hard code it, or write a check into your
builders that's equivalent to what the configure script will do.

I've attached the current version of build_info.c that results from
build_info.pl's processing. I made some significant modifications to
build_info.pl's behavior, so you may notice some other differences as well.

The current --version string I get starts with:

- -----
GNU Wget 1.12.1-devel (e0522c68d1c6) built on linux-gnu.

+digest +https +ipv6 +iri +large-file +md5/openssl +nls +ntlm +opie
+ssl/openssl
- -----

Note; I actually didn't like the whole line-prefixing thing being
applied to feature advertisement, so I had removed it. I had neglected
to fix the comment.
