I propose the included patch.
Notes:
- I used 0 for copyDER. But I don't know what it is used for.
- I have not tested the code. It compiles and all symbols are resolved.
Using libnss 1.8.0.15~pre080614d-0etch1 (from Debian Etch) I can
compile using CERT_NewTempCertificate() but the symbol is not found:
undefined symbol: CERT_NewTempCertificate
(src/mappers/.libs/ldap_mapper.so)
Using __CERT_NewTempCertificate() works but it is not a nice name
Using libnss 3.12.0-5 (from Debian Lenny, released soon) I can use
CERT_NewTempCertificate(). I do not plan to support Etch.
Does the patch looks good for you Bob?
