Good news: With latest libintl and libiconv, gettext-0.16 builds OOB.

Bad news, I appear to have hit a bug in aclocal.  From a fresh checkout
of m4 CVS HEAD:

After which ./configure barfs about unexpanded macros.  I came up
with a crude workaround:

$ fgrep m4_include aclocal.m4 | wc -l
      94
$ ls -1 ltdl/m4/*.m4 | wc -l
     109
$ for file in ltdl/m4/*.m4; do
> grep m4_include aclocal.m4 | grep -q $file || echo missing $file
> done
missing ltdl/m4/argz.m4

$ for file in ltdl/m4/*.m4; do

$ fgrep m4_include aclocal.m4 | wc -l     109

And then everything is fine (including a well behaved M4 make check!)
