Portability fixes:

 - removed "-traditional-cpp" from the darwin6 compile flags, as it broke
   compilation with gcc-3.3 on Mac OS X and does not seem to be required 
   in general.
 - make sure to link libmysqld/examples/mysqltest.c with a C++ compiler, 
   as the embedded server library (libmysqld.a) includes C++ code. This
   broke compilation with non-gcc compilers.
