Hi Chao Zhang,

Although casting also silences the warning, why not declare
CertCommonName as CHAR8 directly? The only signedness check happens
in X509GetCommonName(). Sha256Update() requests "VOID *" so the
signedness doesn't matter. Besides, AsciiStrLen() also requests
CHAR8, so declaring CertCommonName as CHAR8 can remove the casting
altogether. What do you think?

Agree. It's better to use CHAR8 directly.

Could we get this fixed please? The GCC build has been broken for two days now.
