This switches the default behaviour of crashpad_handler.exe to be a /subsystem:windows app, so that normal usage won't cause a console to be popped up. At the same time, creates a copy of crashpad_handler.exe in the output dir named crashpad_handler.com. The .com doesn't affect normal operation, as the way StartHandler() uses CreateProcess() requires a real path to a file. However, when run from a command prompt, .com are found before .exe, so editbin the .com to be to a console app, which will be run in preference to the exe when run as just "crashpad_handler", as one tends to do from a command prompt when debugging. That is: d:\src\crashpad\crashpad\out\Debug>where crashpad_handler d:\src\crashpad\crashpad\out\Debug\crashpad_handler.com d:\src\crashpad\crashpad\out\Debug\crashpad_handler.exe d:\src\crashpad\crashpad\out\Debug>crashpad_handler --help Usage: crashpad_handler [OPTION]... ... d:\src\crashpad\crashpad\out\Debug>crashpad_handler.exe --help <no output> d:\src\crashpad\crashpad\out\Debug>crashpad_handler.com --help Usage: crashpad_handler.com [OPTION]... ... We also use the .com file in test invocations so that output streams will be visible.
