Comment (by ballapete):

 The many failures to test on `Leopard` or `Tiger` come using any of these
 three compiler warnings that `GCC 4.2` does not understand: `-Wno-unused-
 variable -Wno-unused-parameter -Wno-uninitialized`.

 IMO this is a -non-brainer. The warnings are OK when `developing` a
 software, not when `using´ it, for example in a test case. When perfoming
 `make test` they should disappear.
