OK, Hub, now I'm really stumped. The version of Makefile.abi checked into
CVS is *definitely* busted. See below.
Is *your* view of the libiconv tree in sync with what's in CVS? If you do a
"make realclean" does it really build for you? How?
I just ran through the entire build only to have it refuse to link because
none of the following libiconv symbols were found:

Note that it's looking for both versions of the iconv name decorations,
which suggests that we need LIBICONV_PLUG defined *everywhere* that iconv.h
is included (libiconv, wv, and abi trees for now), or nowhere. And
shouldn't that setting be done in platform makefiles, instead of in XP?
Anyhow, digging to find out why the symbols aren't there, here's the
relevant config and make output for libiconv.

Note that it's complaining about a main() function, which no respectable
library should have. Digging a bit further, I realized that Makefile.abi is
currently *only* building the command-line wrapper (src/iconv.c) and
*nothing* in the library (lib/iconv.c).
IIRC from when I messed with this yesterday, I started making headway by
compiling the right file and/or removing the LIBICONV_PLUG definition, only
to realize that none of the necessary header files had been generated
either.
That's when I started asking questions. ;-)
In short, the various makefiles supplied with libiconv 1.7 are doing *much*
more work than Makefile.abi does, so it's no wonder this isn't working.
bottom line
-----------
Getting 0.9.1 out there is very desirable, but I'd hold off on announcing
the 0.9.1 sources, since it's not clear to me how buildable they are.
