Subject: [PATCH 4/4] cpp: Ensure correct expiration time on 32-bit arch with
64-bit time_t
* lang/cpp/src/key.cpp (Subkey::expirationTime): Cast away the
signedness of _gpgme_subkey.expires before casting to time_t.
--
_gpgme_subkey.expires stores the expiration as `long int` although the
expiration is always an unsigned value. Casting the value to unsigned
long int before casting it to time_t ensures that we get the correct
expiration value for 64-bit time_t even on 32-bit systems. With signed
32-bit time_t we still get a negative value as before.
