Yes it does say the following:

If you get tired of typing  "target=i386-mingw32" all the time, then before
you exec the GNUstep.sh script, just set the GNUSTEP_HOST:

  export GNUSTEP_HOST=i586-pc-mingw32
  . $GNUSTEP_SYSTEM_ROOT/Makefiles/GNUstep.sh

And a simple mind, as I am one might think after that the setting
GNUSTEP_HOST would be equivalent to supplying target=XX which it is not.
So just for those stupid ones that take thinks just as they read out,
please correct those lines.

I haven't tried to compile anything recently on mingw, so it's possible 
something has changed.


The question is, why is this not working out for me? There is also the
question if as the mail from Richard seems to suggest I am just too dump
to get it running, or if there is a real problem. Actually I don't mind
that tone of voice, as I happen to know Richard, but to another user of
GNUstep faced with a similar problem I would not find this appropriate.

GNUstep under mingw is basically un-tested Stephan Brandon and Richard 
did get it running, but as far as I know there are not many other 
positive reports on this. I tried to get it working using the 
complie-mingw script from Stephan, which I did adjust to my needs. And I 
also think that I have enough GNUstep (and MS Windows) experience to 
tell that if I run into trouble something most be broken with GNUstep on 
MS Windows.

For me it was not possible to build it without downloading the libxml2, 
as the compilation would just stop. As these might also be caused by the 
specific Windows version each of us is using, here is mine: W2000 
Professional with a current cygwin and a mingw from November.

When runnin objdump I get the following:
$ objdump -t 
c:/users/kiefer/GNUstep/cygwin/usr/GNUstep/System/Libraries/ix86/mingw32/gnu-gnu-gnu/libgnustep-base.a 
| grep private
[  7](sec  5)(fl 0x00)(ty   0)(scl   2) (nx 0) 0x00000000 
__imp____nszone_private_hidden_default_zone

kiefer@XANTHUS ~/GNUstep/core/base/Testing
$ objdump -t 
c:/users/kiefer/GNUstep/cygwin/usr/GNUstep/System/Tools/ix86/mingw
32/gnu-gnu-gnu/gnustep-base.dll | grep private
[21206](sec  2)(fl 0x00)(ty   0)(scl   2) (nx 0) 0x00036664 
___nszone_private_hidden_default_zone

This looks like there is one more underscore in the exported variable 
than expected.

Cheers Fred
