If there any defines required the default way is to create header and to 
place the defines in there. Some checks place the define in the cache, 
which isn't the prefered way.


What about non configure checks which requires non standard definition 
like bzip2 ?

        if env['CACHED_LIBBZ2']:
            dest.write('#define HAVE_BZIP2_SUPPORT 1\n');
            if not conf.CheckFunc('bzDecompressInit'):
                dest.write('#define NEED_BZ2_PREFIX 1\n');
        else:
            print 'libbz2 not found.'

You may take a look into kdelibs\scons-local-0.96.91\SCons\Conftest.py
