	general-purpose setuid wrapper

	header files etc. written for linux, compiles ok on solaris 2.6

	compile using a command like this:
		gcc -DPROG=\"/usr/local/bin/blah.sh\" -o blah wrapper1.c
	then set permissions on the resulting binary to be owned by root
	and have the setuid bit turned on.

	any parameters on the command line when the compiled wrapper is
	run will be passed along to the script or program being run.
