In terms of name space muddying, i think it would be better to call
these variables cyg_hal_argv, and cyg_hal_argc. They are more
generic. Its possible that in the future other synthetic targets may
appear, eg OpenBSD, NT, etc all of which could use these generic
names.

Hummm. Have a look at
/packages/language/c/libc/stdlib/current/src/getenv.c. There is
already a global variable

externC char **environ;

so maybe you can also get this from the invocation code as the third
parameter and set it.
