<sys/stat.h> contains the following:

int	stat __P((const char *, struct stat *))	__RENAME(__stat13);
int	fstat __P((int, struct stat *))		__RENAME(__fstat13);


<sys/cdefs.h> defines __RENAME as:

#ifdef __GNUC__
#define	__RENAME(x)	__asm__(___STRING(_C_LABEL(x)))
#else
...
#endif

you can run down the defiunitions of ___STRING() and _C_LABEL(), or
you can just run the code through cpp and look at the result..

int	stat (const char *, struct stat *) __asm__("__stat13");

this is a GNU C extension which means "for the language-visible function
"stat", use "__stat13" as the assembler/linker-visible symbol.

The m3 translation of <sys/stat.h> will have to arrange for the symbol
used in external linkage to differ from the language-visible name...
or you'll need a M3 stub which calls a C language routine in the M3
run time library which calls the C "stat" routine..

I don't know M3 very well so i'm not sure what's easier.
