+** Fix problems building with the i586-mingw32msvc cross-compiler
+It's now possible to build Guile for Windows by using the
+i586-mingw32msvc cross-compiler on GNU/Linux.  This kind of build
+produces DLLs and a main program that can be copied to and used on a

 Cross building Guile  =====================================================
-As of guile-1.5.x, the build process uses compiled C files for
-snarfing, and (indirectly, through libtool) for linking, and uses the
-guile executable for generating documentation.
+Guile can be cross-compiled for Windows using the i586-mingw32msvc
+cross-compiler.  To do this, you first need to cross-build Guile's
+prerequisites - GNU MP and libtool/libltdl (as described above) - and
+then cross-build Guile itself.
+For each of these steps, configure using an invocation like this:
+CPPFLAGS=-I/usr/local/i586-mingw32msvc/include \
+LDFLAGS=-L/usr/local/i586-mingw32msvc/lib \
+GUILE_FOR_BUILD=/usr/local/bin/guile \
+./configure --prefix=/usr/local/i586-mingw32msvc --host=i586-mingw32msvc
+Then run `make' - which should complete without any errors - and `sudo
+make install'.  (`make check' doesn't work when cross-compiling,
+because the built DLLs and program cannot be run on GNU/Linux.)
+The `GUILE_FOR_BUILD=...' setting is needed because some later steps
+of the build process use Guile itself.  In the non-cross-compiling
+case this is the version of Guile that has just been built.  When
+cross-compiling, you have to set GUILE_FOR_BUILD to tell the build
+where it can find a native version of Guile, to use for these steps.
-When cross building guile, you first need to configure, build and
-install guile for your build host.
+Cross-compiling for other hosts may also work, using the following
+instructions; but this has not been recently tested.
-Then, you may configure guile for cross building, eg:
