I've being trying to compile earl chew's stdio using the POSIX header files
recently posted. Among the problems encountered there is the following:

In POSIX/usr/include/fcntl.h creat is declared as:
	_PROTOTYPE( int creat, (char *__path, int __mode)       	);
  ie	int creat(char *__path, int __mode);
Where as Earl has declared it as:
	int	creat    P((const char *, mode_t)); /* create a file */
  ie	int creat(const char, mode_t);
The two key differences are:
	1. const
	2. mode_t
Which is correct? I suspect that the correct one should be:

	_PROTOTYPE( int creat, (const char *__path, mode_t __mode)     	);
ie	int creat (const char *__path, mode_t __mode);

(Yes I know that the names __path & __mode are optional but they are still
nice :-)

any thoughts?

BTW:	This testing is being done using gcc.
	The above form of macro expansion apparently the `done thing' for
	doing prototype declarations. (It is different to the method originally
	used.
	Some other problems encountered were:
		- missing , ... (optional third arguments) etc
		- files incorectly or not included
		- declarations containing syntax errors
		- fiddling so that the correct compiler is used.
