Building lmdb on illumos fails with the following error:

mdb.c: In function 'mdb_env_copythr': mdb.c:9036:6: error: too many arguments to function 'sigwait' sigwait(&set, &tmp); ^ In file included from mdb.c:132:0: /usr/include/signal.h:165:12: note: declared here extern int sigwait(sigset_t *); ^

This happens because to use sigwait on illumos, you have to add the -D_POSIX_PTHREAD_SEMANTICS switch to the compiler. Changing the Makefile THREADS line to add the switch solves the problem:

THREADS = -pthread -D_POSIX_PTHREAD_SEMANTICS

FYI, I haven't tested on sun/oracle solaris but I guess it suffers from the exact same problem.
