Windows does appear to have a CommandLineToArgvW function that parses
the command line (or whatever string you give it).  I don't know
whether GNAT uses it.  I'm pretty sure that not all C compilers use
it---the MINGW32 version, I believe, does its own parsing, in whatever
startup routine is linked into the program before main() is called.
