1. C problem with getenv under AIX

I'm posting here as well as comp.lang.c as I wonder if this is an AIX
problem.

I have AIX C and am trying to use the function getenv. This is the
compile time error I get:
""tmp.ec", line 13.8: 1506-068 (W) Operation between types "unsigned
char*" and "int" is not allowed.

And here is the code. From my reading I have declared the variable to
take the return value of getenv() correctly.

Any suggestions appreciated. Well here's the code

#include <string.h>
#include <stdio.h>
#include <stdarg.h>

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

homedir=getenv("HOME");
