Shouldn't this be

extern const modssl_sesscache_provider modssl_sesscache_shmcb;
extern const modssl_sesscache_provider modssl_sesscache_dbm;

#ifdef HAVE_DISTCACHE
extern const modssl_sesscache_provider modssl_sesscache_dc;
#endif

?

Shouldn't this be

extern const modssl_sesscache_provider modssl_sesscache_mc;

?
