[Alan Coopersmith]

Gets rid of 16 instances of gcc 4.8 warnings:

In file included from dmxgc.c:41:0:
dmx.h:327:23: warning: assignment discards ‘const’ qualifier from
 pointer target type [enabled by default]
     (_saved)->_entry  = (_actual)->_entry;    \
                       ^
dmxgc.h:80:5: note: in expansion of macro ‘DMX_WRAP’
     DMX_WRAP(funcs, &dmxGCFuncs, _pGCPriv, (_pGC));   \
     ^
dmxgc.c:192:5: note: in expansion of macro ‘DMX_GC_FUNC_EPILOGUE’
     DMX_GC_FUNC_EPILOGUE(pGC);
     ^
