You do it something like this. Note the argument to --host MUST NOT match what sh config.guess returns. ./configure CC=cc CFLAGS="-Xa -fast -xstrconst -xchip=ultraT3 -xarch=sparcvis3 -mt -m64" --host=sparcvis3-sun-solaris2.10 --with-randomdev=/dev/random --with-ecdsa=no --with-gost=no BUILD_CC

You might want to look at the output of: dig axfr example.com This gives also the contents of the zone, nicely sorted but with an added SOA at the end. I would suggest to use it for comparison with the files to look for some of those interesting endings (~~.com\032.) Those really look odd to me.
