CXXFLAGS =  -O2 -I/usr/X11R6/include -I/usr/include/gtk-1.2 
-I/usr/include/glib-1.2 -I/usr/lib/glib/include -I/usr/X11R6/include 
-fno-merge-constants
^^ thats what I modified, which brings the same problem (same error). 
removing also the -fno-merge-constants make B2 screams "floating point 
exception".

I tried to compile with and without DGA support - same error.

Actually, it doesn't work well - I get on the "mac" - "sorry, a system error 
occured. "system" "illegal instruction" 
And on the console: Illegal instruction: 000b at 00034888
Thats on the 68030 with FPU, or with 68040. With the 68040 mode I get at the 
console: Illegal instruction: 000b at 0003c9dc

./configure --disable-xf86-vidmode --enable-fpe=uae --disable-xf86-dga gives 
the exact same error.

Now trying with your patch:

Any other ideas?

I'm on IRC in irc.kde.org server (on channel #winehq) - feel free to contact 
me and I'll let you in to 1 of my machines if you want to test or change B2..

Thanks,
