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.
