I don't see any of these with 10.6.8 (with either clang or
the Apple gcc). Do they appear to be legitimate warnings?

Hmm, I hadn't tried running make check. I see:
(a) tests randomly hang (possibly only if built with gcc? hmm)
(b) test-string-input-visitor(59002) malloc: *** error for object
0x12068: pointer being freed was not allocated
(c) test-thread-pool seems to hang
(d) make distclean doesn't delete the test executables in test/ :-)
(e) lots of format-security warnings from check-qjson.c:
tests/check-qjson.c:53:33: warning: format string is not a string
literal (potentially insecure) [-Wformat-security]
        obj = qobject_from_json(test_cases[i].encoded);

I'll prod a bit further on (b) at least...
