Is it possible to disable the thread facilities with a #define?

% uname -a
SunOS mcfsrv 5.8 Generic_108528-08 sun4u sparc SUNW,Ultra-Enterprise
% gcc --version
3.0.4
% gcc -print-libgcc-file-name
/home/users2/nksauter/local/gcc304/lib/gcc-lib/sparc-sun-solaris2.8/3.0.4/libgcc.a

As far as I can tell this libgcc.a came with the gcc 3.0.4 distribution.

Thanks,
        Ralf
