Jacek Caban (@jacek) commented about include/msasn1.h:
typedef ASN1uint32_t ASN1magic_t; typedef ASN1ztcharstring_t ASN1objectdescriptor_t;
+#define ASN1_PUBLIC __declspec(dllimport)
We still need to support non-PE targets, so using __declspec like this is problematic. This should probably just use DECLSPEC_IMPORT.
