+Subject: [PATCH] fix build with libressl >= 3.5.0
+
+`DSA_METHOD` is opaque since libressl 3.5.0 and
+https://github.com/libressl-portable/openbsd/commit/62c7bff5397fa44f595b161cd593d9456eca236e
+resulting in the following build failure:
+
+```
+pkcs11h-openssl.c: In function 'DSA_meth_set1_name':
+pkcs11h-openssl.c:239:41: error: invalid use of incomplete typedef 'DSA_METHOD' {aka 'struct dsa_method'}
+  239 |  rv = _pkcs11h_mem_strdup ((void *)&meth->name, name);
+      |                                         ^~
+```
