commit 9b78a4bf59d87412ae29a1af918f345182502309
Author: David M. Lee <dlee@respoke.io>
Date:   Wed Dec 27 23:47:14 2017 -0600

    Various fixes for macOS
    
     * Removed bundle1.o and macosx-version-min. This is unnecessary, and
       become dated more quickly than we update macOS support (10.6 has been
       EOL for over three years)
     * Add some explicit casting to fix clang errors/warnings
     * Fix when strlcat and strlcpy are macros
     * Ignore self-assign errors, because macros
     * Ignore tautological errors in AST_VECTOR_INSERT_AT(), because macros
     * Fix warnings for taking the difference of unsigned values
     * Fix #ifdef logic around sysinfo and swapctl
     * Fix some sign and type nits that clang complains about
