Sorry -- I was starting to do some testing, but got distracted by some 
side issues:
   (1) building libbfd/libopcodes as DLL on windows (with the new 
libtool support).  This is related to:
   (2) using the new libtool to build libiberty
Warning on #2: I dug up an old (gcc-patches mailing list, circa Oct 
2004) attempt at this, and used it with some limited success.  However, 
there are /issues/ with making libiberty into a libtoolized 
"convenience" library.  See this thread:

[RFC] New library "type" needed?
http://lists.gnu.org/archive/html/libtool/2007-03/msg00022.html

especially the final post:
Simultaneous pic and non-pic convenience libs [Was: [RFC] New library..]
http://lists.gnu.org/archive/html/libtool/2007-03/msg00038.html

I'll rip that failed experiment out of my tree and try again with just 
Steve's patches; however I'd imagine Dave Korn will have results before 
I do.
