   FUNCTION
	Deletes a local or environment variable.

   INPUTS
	name   - pointer to an variable name.  Note variable names follow
		 filesystem syntax and semantics.
	flags  - combination of type of var to delete (low 8 bits), and
		 flags to control the behavior of this routine.  Currently
		 defined flags include:

		 GVF_LOCAL_ONLY  - delete a local (to your process) variable.
		 GVF_GLOBAL_ONLY - delete a global environment variable.

		 The default is to delete a local variable if found, otherwise
		 a global environment variable if found (only for LV_VAR).

	success - If non-zero, the variable was sucessfully deleted, FALSE
		  indicates failure.

   BUGS
	LV_VAR is the only type that can be global
