I can imagine that cross-compiling would be hard, since it wants to run
guile during the build process.  You might be able to modify the
guile-preinst to point to some other working native version of guile.

I originally got a static version working, and I think the version that
comes with lilypond is static.  Being rather bullheaded and wanting shared
libraries, I pounded and tweaked on it until I got a DLL version to build.
It loads extensions dynamically fine, anyway.

Just as a warning, it doesn't build cleanly out of the box even with this
patch.  One problem (which could be patched but isn't) is the link step of
libguilereadline.la depends on ../libguile/libguile.la, which isn't built
by the libguile build.  It creates it in the ../libguile/.libs/ directory.
Another has to do with the winsock2.h include; the Makefile.in checks for
it but including it under cygwin conflicts with other network headers.
There is a similar issue with HAVE_ERRNO_H.

The autobuild.sh file came from a patch by Gerrit P. Haase on the that I
found on the lilypond wiki site.  (http://lilypond.org/wiki/?GuilePatch).
It has several items about building guile on cygwin, as does the cygwin
mailing list archive (google is your friend :-).

I think the differences in libltdl are because I copied the version from
libtool 1.4d there.  Libtool ersion 1.4.2 didn't get it to go, and I don't
recall what came with Guile.
