RFR(XXS): 8168471: Non ANSI C declaration of block local variable in NetworkInterface_winXP.c

[Volker Simonis]

Hi,

can I please get a review for the following trivial fix:

http://cr.openjdk.java.net/~simonis/webrevs/2016/8168471/
https://bugs.openjdk.java.net/browse/JDK-8168471

Change "8168405: Pending exceptions in java.base/windows/native"
introduced the following non ANSI C compatible code for declaring a
block-level variable ("jboolean ret"):

} else /* AF_INET6 */ {
    int scope;
    iaObj = (*env)->NewObject(env, ia6_class, ia6_ctrID);
    if (iaObj == NULL) {
        return NULL;
    }
    jboolean ret = setInet6Address_ipaddress(env, iaObj, (jbyte
*)&(addrs->addr.sa6.sin6_addr.s6_addr));

But ANSI C only allows the declaration of block local variable at the
beginning of a block.Unfortunately some still very common compilers
like Microsoft VS2010 and VS2012 still don't support this C99 feature
:(

Thank you and best regards,
Volker
