Thusly on 11.0:


 utimes(2)                                                        
utimes(2)

 NAME
      utimes - set file access and modification times

 SYNOPSIS
      #include <sys/time.h>

      int utimes(const char *path, const struct timeval times[2]);

and then in sys/time.h:

#  ifdef _PROTOTYPES
     extern int getitimer(int, struct itimerval *);
     extern int setitimer(int, const struct itimerval *, struct
itimerval *);
     extern int utimes(const char *path, const struct timeval
amtimes[2]);
     extern int gettimeofday(struct timeval *, void *);
#    if defined(__INCLUDE_FROM_TIME_H) &&
!defined(_XOPEN_SOURCE_EXTENDED)
       extern int select(size_t, int *, int *, int *, const struct
timeval *);
#    else       /* __INCLUDE_FROM_TIME_H && !_XOPEN_SOURCE_EXTENDED */
       extern int select(int, fd_set *, fd_set *, fd_set *, struct
timeval *);
#    endif      /* __INCLUDE_FROM_TIME_H && !_XOPEN_SOURCE_EXTENDED */
#  else /* !_PROTOTYPES */

Perhaps the use of const in the UX headers is the trigger for this?

If there is a utimes on the platform, should that bsd-misc.[ch] stuff
even be included? Or does the configure script for ssh consider utimes
broken under HP-UX?

The compiler (at least my rev) doesn't mind the omission of the variable
name:

$ cat foo.h
int utimes(char *, int *);
$ cat foo.c
#include "foo.h"
int utimes(char *filename, int *tvp) {
}

main(int argc,char *argv[]) {
}

(I dropped the timeval stuff initially to avoid having to include more)

However, when I then add-back the struct timeval, and include
sys/time.h:

$ cat foo.c
#include <sys/time.h>
#include "foo.h"
int utimes(char *filename, struct timeval *tvp) {
}

main(int argc,char *argv[]) {
}

I get:

$ cc foo.c
cc: "foo.h", line 1: error 1711: Inconsistent parameter list declaration
for "utimes".
cc: "foo.c", line 3: error 1711: Inconsistent parameter list declaration
for "utimes".

and then if I add const:
$ cat foo.h
int utimes(const char *, const struct timeval *);

$ cat foo.c
#include <sys/time.h>
#include "foo.h"
int utimes(const char *filename, const struct timeval *tvp) {
}

main(int argc,char *argv[]) {
}

the compiler is happy:

$ cc foo.c
/usr/ccs/bin/ld: (Warning) At least one PA 2.0 object file (foo.o) was
detected. The linked output may not run on a PA 1.x system.
