I posted this once, but it disappeared.  Oh well.

I have a project I inherited with ~300,000 lines of sloppy non ANSI C code
in about 250 files.  I want to make this code ANSI compliant in preparation
for a conversion to C++, at which point, hopefully, I can reuse much of this
code.  In switching to GNUC gcc version 2.4.5 from the SUN C compiler under
SunOs 4.1.1, I discovered protoize, which does a great job of generating
ANSI function declarations for old C code.  However, it doesn't do two
things I would like it to, or I am missing some options.

	a) generate a prototype at the top of a source file if a function
	   is used/explicitly declared before the true declaration at the
	   beginning of a function.

		Example:

		(before protoize)
		void foo() {
			bar();
		};
		
		static void bar() {
		};

		(after protoize)
		void foo(void) {
			bar();
		}
		static bar(void) {
		};

		There is no prototype, even using the -l option with protoize, and
		the compiler still bitches.

	b) detect a function declaration with the wrong return type. 

		Example:

		foo() {
			long l;
			return l;
		};

		this isn't caught by protoize, either.  I haven't run it through
		lint to see the results there, but I am sure lint will catch it.

It would be very time consuming to do ~250 modules by hand, so I was wondering
if there was something to help with this along with protoize... Any suggestions?

All advice appreciated.
