** Have `scm_take_locale_symbol ()' return an interned symbol (bug #25865)
** Fix potential deadlocks when running on multiple threads
** 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
Windows PC. For how to do this, see the `Cross building Guile'
section in `README'.

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.
When cross building guile, you first need to configure, build and
install guile for your build host.
For each of these steps, configure using an invocation like this:
Then, you may configure guile for cross building, eg:
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.
Cross-compiling for other hosts may also work, using the following
instructions; but this has not been recently tested.
To configure Guile for cross building, for example for Cygwin:
./configure --host=i686-pc-cygwin --disable-shared
