If I pass in a STACK_OF(X509) *certs with only the signer's cert in it, and NULL for X509_STORE *st since it won't be used, then I think I should get the desired result, yes, at the cost of ocsp_find_signer(single-entry certs) and the internal creation/destruction of an unused X509_STORE_CTX. I'd have a small performance hit but it probably wouldn't be too bad. The alternative would be to change the OCSP_BASICRESP_verify() macro into an externally available function, and then both it and OCSP_basic_verify() could call the former macro, suitably renamed and internally scoped. Clearly I'd be happy with that, though I understand if you don't want to go that route.
