35 * This module uses several "new" interfaces, among which is
36 * CertGetCertificateContextProperty. CERT_KEY_PROV_INFO_PROP_ID is
37 * one of possible values you can pass to function in question. By
38 * checking if it's defined we can see if wincrypt.h and accompanying
39 * crypt32.lib are in shape. The native MingW32 headers up to and
40 * including __W32API_VERSION 3.14 lack of struct DSSPUBKEY and the
41 * defines CERT_STORE_PROV_SYSTEM_A and CERT_STORE_READONLY_FLAG,
42 * so we check for these too and avoid compiling.
43 * Yes, it's rather "weak" test and if compilation fails,
44 * then re-configure with -DOPENSSL_NO_CAPIENG.
