    TODO: revise the benchmarking functions below to allow valid comparisons
          between the wx implementation and the system's implementation of
          the tested functions (e.g. adding tests which use the wxS macro to
          avoid runtime encoding conversions, etc etc).

//
// Profiling under Linux:
// =====================
//
//   1) configure wxWidgets in release mode
//   2) make sure that HAVE_UNIX98_PRINTF is undefined (just #defining it to zero
//      does not work; you must comment out the entire #define) in your setup.h;
//      and also that wxUSE_PRINTF_POS_PARAMS is set to 1; this will force the
//      use of wx's own implementation of wxVsnprintf()
//   3) compile wx
//   4) set wxTEST_WX_ONLY to 1 and compile tests as well
//
// Now you have two main choices:
//
//  - using gprof:
//      5) add to the Makefile of this test program the -pg option both to
//         CXXFLAGS and to LDFLAGS
//      6) run the test
//      7) look at the gmon.out file with gprof utility
//
//  - using valgrind:
//      4) run "valgrind --tool=callgrind ./printfbench"
//      5) run "kcachegrind dump_file_generated_by_callgrind"
