At first: don't post examples with line numbers as one who will try to 
	 	help will have to remove them

Your code is bad. Earlier compilers allowed that, but now gcc-2.95 
generates error by default. You may:
	use compiler command line option -fpermissive to get warnings
	instead (don't ask to make in the default, it will not happen)

	fix the code:
		for example 'void gp_cursor(const gp_cur & c)' must help. Of
              course if You're not modifying c there. Or create temporary
	       variable
