../../libunwind/src/UnwindLevel1-gcc-ext.c:172:47: error: cast from 'const unsigned int *' to 'unsigned int *' drops const qualifier [-Werror,-Wcast-qual]

  ex.pr_cache.ehtp = (_Unwind_EHT_Header *) unwindInfo;

I don't see any reason there should be a const here in the first place,
so just remove it.
