Minor nag: APR build warnings on Solaris

During build and test for the 1.7.1-rc2 release vote I noticed the 
following warnings, but only for Solaris 10 Sparc. None is new, they 
were already present at least for 1.7.0:

locks/unix/proc_mutex.c:979:49: warning: 
'mutex_proc_pthread_cond_methods' defined but not used 
[-Wunused-const-variable=]

and in the tests:

test/testatomic.c:331:56: warning: format '%lu' expects argument of type 
'long unsigned int', but argument 3 has type 'apr_uint64_t' {aka 'long 
long unsigned int'} [-Wformat=]
test/testatomic.c:345:57: warning: format '%lu' expects argument of type 
'long unsigned int', but argument 3 has type 'apr_uint64_t' {aka 'long 
long unsigned int'} [-Wformat=]

Best regards,
