INTERNAL_FUNCTION

SYNOPSIS
	void bfd_check_init(void);

DESCRIPTION
	This routine is called before any other libbfd function using
	initialized data. It ensures that the structures have
	been initialized.  Soon this function will go away, and the bfd
	library will assume that <<bfd_init>> has been called.
