errors when compiling hide.c on hp unix

Hello,
has any of you guys scucessfully compiled the hide.c on HP-UX. Just to refresh memories, It is a c program that hides the password that hides the password when sqlplus etc command line utilites are run with password as input.
here is the errors I get when I compile it.

cc -o hide hide.c

I was able to compile it on aix,

The original source code of hide.c is below. Any help is appreciated.Thanks.

 |      Can be used as a program prefix: hide program arguments       
     |
 |      or as a symbolic link.  If this program is not invoked as
hide, it  |
 |      will hide its arguments and invoke the program name.hide      
     |
 |      The best way to use this is to rename your critical programs
to     |
 |      program.hide, and create a symbolic link program to hide.     
     |
 |      mv sqlplus sqlplus.hide; ln -s hide sqlplus                   
     |
 |      Thus when sqlplus is invoked, its arguments will be hidden    
     |
 |   NOTES                                                            
     |
 |      This program works by padding 3000 '/' chars in argv[0].  This
fools|
 |      all known ps's.  This will reduce the argument capacity of
your     |
 |      program by 3000 chars.  A good enhancement would be to reduce
the   |
 |      padding if needed so that no arguments are lost - would
require a   |
 |      method of determining the max argument size on the system. 
Some    |
 |      system's provide the E2BIG error on exec.                     
     |
 |      There is some performace penalty for using this program, but
it is  |
 |      minimal because this program is so small - the biggest cost is
the  |
 |      extra exec required to get this program started.

• Added exit(1) when cannot execvp the program. *
• Revision 1.5 1992/09/22 11:28:44 dbeusee
• SOme BSD systems have memset(), so add a #define memset MEMSET to fix

• BSD systems need memset routine. *
• Revision 1.3 1992/09/22 06:05:13 dbeusee
• Set JUNK_CHAR to ' ' but force last junk char to '/'. This looks prettier
• when doing 'ps'. Also do not show full path of the program. Also do not
• show .hide if prog is a symlink to hide. *
• Revision 1.2 1992/09/22 05:52:26 dbeusee
• If hide could not execvp the program, give an error message.
• if hide was invoked with a full path (e.g. /usr/local/bin/hide),
• do not try to invoke PATH/hide.hide. * * */ #include <stdio.h> #ifdef SYS5 #include <string.h> #else #include <strings.h> #define strrchr rindex #define memset MEMSET /* some BSD systems have a memset() */ char *memset(); #endif #define JUNK_SIZE 3000 #define JUNK_CHAR ' ' char arg0buf[4096]; char progbuf[4096]; char errbuf[4096]; int main(argc, argv) int argc; char *argv[]; { char *name, *base; int firstarg; if (!(name = strrchr(argv[0], '/'))) name = argv[0]; else name ++; /* get past '/' */ firstarg = (!strcmp(name, "hide")) ? 1 : 0; if (firstarg && (argc == 1)) { fprintf(stderr, "Usage: hide program arguments\n"); fprintf(stderr, " ie: hide sqlplus username/password\n"); fprintf(stderr, "if hide is not named hide, \ it will execute name.hide (useful as a symbolic link)\n"); exit(1); } /* Build program name.
