Hi,

please review and sponsor this AIX fix.

in ResolverConfigurationImpl.c, we may crash because strchr() is used without prototype, which causes the C compiler to default to an int return type, which means we loose the upper 32bit of the pointer returned by strchr().

The solution is to include string.h.

Before, string.h was conditionally included for all platforms but AIX - reason is not really clear to me. But as strchr() is POSIX and always in string.h, I included string.h unconditionally for all Unices.
