The CRT source code comes with Visual Studio (probably not with the 
Express Edition). One can download the VS2011 Preview and in it, just 
check the

"C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\crt\src\stdargv.c"

file, then this function (unicode variant here, there is non-unicode too):

static void __cdecl wparse_cmdline()

It could be that it's behaviour is where close to what 
CommandLineToArgcW, but the CRT is not using that function.

Probably so that the CRT does not have dependency on SHELL32.dll (where 
the function comes from).

One thing that MSVCRT implements, if you link with 
setargv.obj/wsetargv.obj (unicode) is some kind of globbing that is 
found in Unixes - I've used it in the past - one has just to add 
setargv.obj somewhere in the linker options.

it's in here, usually part of your LIB env.

C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\lib

Cheers!
