[MPlayer-dev-eng] [PATCH] libvo/gl_common.c: Use RTLD_DEFAULT instead of 0 for dlsym to increase portability

[Jeremy Huddleston]

What about:

#ifdef RTLD_DEFAULT
return dlsym(RTLD_DEFAULT, s);
#else

void *handle = dlopen(NULL, RTLD_LAZY);
void *ret = dlsym(handle, s);
dclose(handle);
return ret;
#endif
