Thanks so much for pointing this out!  All my experience, mostly
successful, with running under wine comes from running in the build
directory.  You indeed seem to have discovered a problem with our
windows installer.  'make install' is supposed to run the following to
setup the system directory paths to their correct final values:

>From the top level makefile:
     
     echo '(reset-sys-paths "$(INSTALL_LIB_DIR)/")(si::save-system 
"$(FLISP)$(EXE)")' | ./temp$(EXE) && \

Don, can you see any reason why this is not happening?

In any case, alas, the detect_wine function is run too early to change
the si::*system-directory*.  I suppose I could have it read an
environment variable by default, or maybe move it to the first use of
'system', which might provide more working room.  Suggestions most
welcome.  In any case, if there is a chance you might build gcl from
source according to README.wine and run from the build directory, I'd
appreciate any feedback on how it goes for you.

The raw image will be of no use to you unless you have access to the
build directory.

msys is just a little helper to run external system commands
synchronously.  My experience with wine was that the native call
returned before the child finished, leading to corrupt gcc .o output,
for example.  From the above lines, yo don't have libansi_gcl.a (I don't
think) installed, so ar cannot produce the needed file to run the
initialization in the raw image.

Hope this is clear enough -- if not, please ask more questions.  I will
think about a detect_wine system-directory escape, and hopefully if you
can you might be able to test from a build directory.

Take care,
