This particular issue isn't covered in those hints, it's an internal
MD5 process which is the same as the internal MD5 code in eglibc.

I could hide the problem by dropping -Werror or adding
-fno-strict-aliasing but it's not clear to me why the same code
compiles in eglibc and not in qof, especially when eglibc is passing
-fstrict-aliasing.

I'm fairly sure that this needs no source code changes in md5.c,
this is something related to the build system options but I have to
admit I can't quite see where it lies currently.

(Due to the history of the code in QOF, exactly the same code still
exists in all versions of GnuCash.)
