signedness issues when compiling with -mno-powerpc

I'm trying to compile libsa under powerpc with the options
-mno-power and
-mnopower-pc.  When these options are applied, lots of
things start complaining
about signedeness of pointers to char's.

One example is in libsa/checkpasswd.c line 121, where we
have:

char *passwd;
MD5Update(&md5ctx, passwd, strlen(passwd));

and according to the manpage: 
MD5Update(MD5_CTX *context, const unsigned char *data,
unsigned int len);

So what is the right fix for this?

My assumption is that each instance of this should be fixed
in the source.  Or
is there a compiler option I should use instead to skip past
these warnings?

generally, those sorts of problems should be fixed in the
code.  if
it is too much of a nightmare, apply -Wno-pointer-sign to
that file
and note it in doc/HACKS (there is a big list already.)

In this particular case, I would say the right fix is to
make MD5Update
take a const void *.

More generally, I would say your assumption

is right.

Check the docs; lots of warnings have -Wno-* forms.
