Lionel Sambuc 84d9c625bf Synchronize on NetBSD-CVS (2013/12/1 12:00:00 UTC)
- Fix for possible unset uid/gid in toproto
 - Fix for default mtree style
 - Update libelf
 - Importing libexecinfo
 - Resynchronize GCC, mpc, gmp, mpfr
 - build.sh: Replace params with show-params.
     This has been done as the make target has been renamed in the same
     way, while a new target named params has been added. This new
     target generates a file containing all the parameters, instead of
     printing it on the console.
 - Update test48 with new etc/services (Fix by Ben Gras <ben@minix3.org)
     get getservbyport() out of the inner loop

// A note about the lutok::state tests.
//
// The methods of lutok::state are, in general, thin wrappers around the
// corresponding Lua C API methods. The tests below are simple unit tests that
// ensure that these functions just delegate the calls to the Lua library. We
// do not intend to test the validity of the methods themselves (that's the
// job of the Lua authors). That said, we test those conditions we rely on,
// such as the reporting of errors and the default values to the API.
//
// Lastly, for every test case that stresses a single lutok::state method, we
// only call that method directly. All other Lua state manipulation operations
// are performed by means of direct calls to the Lua C API. This is to ensure
// that the wrapped methods are really talking to Lua.
