Hi

The "token" structure defined in:
    src/lib/krb5/os/expand_path.c
conflicts with a structure generated by GCC 6.3.0 on AIX which appears in:
    /opt/freeware/lib/gcc/powerpc-ibm-aix6.1.0.0/6.3.0/include-fixed/net/if=
_arp.h

I've attached a very simple patch that suppress this issue on AIX (and mayb=
e on other OS).

-static const struct token {
+static const struct krb5_token {


Regards,

Tony
