compile error on aix 5.1 with gcc

[Breuer, Marcel]

Hello *,

I tried to compile the MIT kerberos source  and got the following error:

_F -DLOGIN_CAP_F -DLOGIN_PROGRAM=KRB5_PATH_LOGIN -I../../../include
-I./../../../include  -I../../../include/krb5 -I./../../../include/krb5 -I..
-I./.. -I./../../../include/kerberosIV -I../../../include/kerberosIV   -g
-O2 -Wall -Wmissing-prototypes -Wcast-qual  -Wcast-align -Wconversion
-Wshadow -Wno-comment -pedantic -c forward.c

The server OS : AIX 5.1
gcc 3.3.2
autoconf 2.59
m4 1.4
krb5-1.3.1

The error message
usr/local/lib/gcc-lib/powerpc-ibm-aix5.1.0.0/3.3.2/include/stdlib.h:480:
error: previous declaration of `setenv' refers perhaps to:
.....

        extern float    strtof();

*);
        extern int      on_exit(void (*)(int, void *), void *);
#endif /* ifdef _NO_PROTO */

........

I found no useful hint in the net. Are there any special
prerequisites(packages or something else) for compiling kerberos under AIX?

Thank you!

Sincerely,

Marcel Breuer
