libiberty/md5: fix strict alias warnings
Current libiberty md5 code triggers these warnings with gcc-4.7.1 for me:
libiberty/md5.c: In function âmd5_finish_ctxâ:
libiberty/md5.c:117:3: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
libiberty/md5.c:118:3: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
The change below fixes things for me. The optimized output (-O2) is the same
before/after my change on x86_64-linux. I imagine it'll be the same for most
targets. It seems simpler than using a union on the md5_ctx buffer since these
are the only two locations in the code where this occurs.
