REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1089 When building CryptoPkg with Clang, blow error may result * /usr/lib/llvm-3.8/lib/clang/3.8.0/include/stdatomic.h:105:17: error: unknown type name 'wchar_t' Since the C native atomics are C11 feature we can explicitly use C99 to work around it. add -std=c99 to avoid it * openssl/crypto/conf/conf_sap.c:71:12: error: variable 'ret' is uninitialized when used here [-Werror,-Wuninitialized] Suppress warnings in OpenSSL so we don't break the build with -Werror. add -Wno-error=uninitialized to disalbe this warning Cc: Ting Ye <ting.ye@intel.com> Cc: Jian J Wang <jian.j.wang@intel.com> Signed-off-by: Xiaoyu Lu <xiaoyux.lu@intel.com> Reviewed-by: Jian J Wang <jian.j.wang@intel.com>
