please include these changes

Hi, these two patches fix a couple of issues. The AM_CONFIG_HEADER macro is obsolete and actually causes an error in recent autotools.

The other fix is for builds on Mac OS X, where symbols are not defined unless _POSIX_SOURCE is set. The strings.h include is required because of strncasecmp.

I believe that these changes will not hurt the Linux builds in any way, but if they do, another fix could be made that only affects Mac OS X builds.

Thanks,

Dennis
