gspawn-win32-helper.c has a nice comment about this issue:
/* We build gspawn-win32-helper.exe as a Windows GUI application
 * to avoid any temporarily flashing console windows in case
 * the gspawn function is invoked by a GUI program. Thus, no main()
 * but a WinMain(). We do, however, still use argc and argv tucked
 * away in the global __argc and __argv by the C runtime startup code.
