I'd say to define __EXTENSIONS__, but see that it's done.  Sun's compiler
doesn't mind the declaration, which is in stdio.h:

#if defined(__STDC__)

#if     defined(__EXTENSIONS__) || defined(_REENTRANT)
extern char     *tmpnam_r(char *);
#endif /* defined(__EXTENSIONS__) || defined(_REENTRANT) */
#if defined(__EXTENSIONS__) || (__STDC__ == 0 && \
        !defined(_XOPEN_SOURCE) && !defined(_POSIX_C_SOURCE))
extern void setbuffer(FILE *, char *, size_t);
extern int setlinebuf(FILE *);
/* 
 * These v*scanf functions are part of the C99 standard.  At such 
 * time that the standard is fully implemented, these functions 
 * will be moved to iso/stdio_iso.h. 
 */
extern int vfscanf(FILE *, const char *, __va_list);
extern int vscanf(const char *, __va_list);
extern int vsscanf(const char *, const char *, __va_list);
#endif
