Okay, I now have applied all given patches to the source tree. But I still 
have problems linking qemu. Here is the linker error message:

Okay, fesetround can be resolved by adding '-L/opt/SUNWspro/lib -lm9x' but 
what about the other symbols?

Another thing:
during compilation I get a lot of warnings about fabs which is declared 
inside /opt/SUNWspro/prod/cc/include/sunmath.h:

/home/nardmann/qemu-0.7.0/fpu/softfloat-native.h:171: warning: implicit 
declaration of function `fabsf'

BTW: yes, I am using Solaris 9.
