Good news:  libtool 2.2.2 is now available on Cygwin and seems to handle the 
interlibrary dependencies.

Bad news:  (a) using the new libtool requires running bootstrap (to get new 
ltmain.sh, libtool.m4, ...?), so it still requires a patch (to add 
bootstrap) to work with the current release; and (b) autoconf (and/or 
libtoolize?) produce a number of warnings, such as "LT_OUTPUT was called 
before LT_LANG".  (I think there are some compatibility issues, but I 
haven't found any simple documentation on them yet.)

Unknowns:  I don't know if libtool 2.x runs on MinGW, and I haven't tried it 
on Debian (to see if it gets the same warning messages).
