[krbdev.mit.edu #2839] compilation error on AIX 5.1 and gcc 3.4.4

[sharma via RT]

Hi

I have a compilation error with setenv API redefinition in krb code
./libtelnet/forward.c and system header files on AIX 5.1 with gcc 3.4.4
[2.95 also] compiler.

The message looks like this, for any other information I will happy to
provide you. I hope you are the right person to forward all errors in
future, otherwise let me know.

I looked into the problem and found that in compilation the -DHAVE_SETENV=1
and -DNEED_SETENV=1 are going in and ./libtelnet/forward.c has code like

#include "krb5.h"
#include <errno.h>

#include "krb5forw.h"

#if defined(NEED_SETENV) || defined(NEED_SETENV_PROTO)
extern int setenv(char *, char *, int);
#endif

Redefines the system's prototype which is

extern int  setenv(const char *, const char *, int);
