53 * GetCommandLineA (KERNEL32.@)
55 * WARNING: there's a Windows incompatibility lurking here !
56 * Win32s always includes the full path of the program file,
57 * whereas Windows NT only returns the full file path plus arguments
58 * in case the program has been started with a full path.
59 * Win9x seems to have inherited NT behaviour.
61 * Note that both Start Menu Execute and Explorer start programs with
62 * fully specified quoted app file paths, which is why probably the only case
63 * where you'll see single file names is in case of direct launch
64 * via CreateProcess or WinExec.
66 * Perhaps we should take care of Win3.1 programs here (Win32s "feature").
