 This issue is not only for DragonFly also happend on NetBSD-5.1 without 
optimization CFLAGS.
 
 For __environ, configure check existence of __environ symbol as following:
 
 ======================================================================
 extern void *__environ;
 int
 main ()
 {
 void *tmp = __environ;
    ;
    return 0;
 }
 ======================================================================
 
 On DragonFly-2.8.3, it always failed because of missing __environ symbol.
 But on NetBSD-5.1 with -O2, succeed to link (probably unaffected assignment
 will be removed), with -O0, failed to link and same error as DragonFly will be 
happend.
 
 Real Codecs contains __environ symbol, so even if succeed to build on NetBSD,
 realplayer codec support may be broken feature.
