UPNP_USE_RWLOCK is false (0).

Patch to take notice of UPNP_USE_RWLOCK flag
The configure.ac file included with UPnP checks for the presence of the
pthread_rwlock_t type, and then sets the value of the UPNP_USE_RWLOCK
flag appropriately. However, this flag is not referenced at all in the
source code, and thus the code does not compile on systems that don't
have the pthread_rwlock_t type (such as Android).
Please find attached a patch (against the current 1.6.x head) that checks
the value of this flag and falls back on using mutexes if read-write
locks are not available.

release of libupnp (1.6.6) remotely triggerable by any
