Approximately never, unfortunately.  However we have been improving it
recently, and cross-compiling from GNU systems to MinGW is done

I will mostly address concerns about cross-compiling.  Note that you
should really be using Guile from stable-2.0 git and the latest MinGW.

The easiest way to do that is to install a Fedora 18 VM, because they
package mingw very well and are closest to upstream.  I'm a Debian user
and that's what I did, FWIW.  I haven't yet tried with Debian itself.

Also I would mention that dynamic linking should work on Windows, if all
your DLLs are in the same folder.  But I am ignorant and maybe that
doesn't work.

Are you saying that symbols with internal, static linkage inside bdw-gc
conflict with static symbols inside Guile?  This sounds like a
misconfiguration issue.

FWIW I did not experience this in my cross-compile.

Fixed upstream; thanks.

Are you certain that the meta/guile and meta/guild scripts need the .exe
extension?  They are not EXE files.  MinGW should add on .exe to
programs like libguile/guile (NB: not meta/guile) as needed.

Also note that I just fixed a bug in meta/guile in which it was
referencing libguile/guile without the @address@hidden

Basically I think --program-suffix is not what you want.

This is fixed in git, I believe.

I think we're close.  Can you give it another try?  If needed I can
handle the autogen side of things and give you a freshly prepared
