Me too, using the current configure script with MSYS bash should be no
problem (if there is I'm interested to know where). 

I'd suggest you do a system that attaches to the current system with as
small changes as possible (so you get reviewers) and put all windows
specific things to separate script(s) (which is executed *only* when windows
build is detected). The gnulib dependency could be handled so that in 
case (ext/*)gnulib directory does not exist, first
'git clone git://git.savannah.gnu.org/gnulib.git' is done -- and then
a specific commit is checked out from the clone (git reset --hard <hash>)
This way we get an exact working tree from gnulib but only when someone
attempts to do w32 build (if there are some licensing issues (copyright
assignment papers???) we can require user to manually execute the script
which checks out the repository, maybe with magic command line argument)
A draft of a checkout script is at the end of this email.
(If you desire to build required parts using autotools in your custom
script please do so. In any case nobody will take the responsibility
to support the w32 build :D)
