remove also wxT(); it's confusing, too; do load wxstd.mo catalog after calling wxLoca...

+// 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"
