    Fix deprecation warning for _BSD_SOURCE
    
    When compiling any egg with CHICKEN you get a deprecation warning:
    
    /usr/include/features.h:148:3: warning: #warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE" [-Wcpp]
     # warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE"
    
    On linux, `man feature_test_macros` states that the _BSD_SOURCE macro is
    deprecated in glibc 2.20.
    
    As suggested in the warning defining _DEFAULT_SOURCE makes the warning
    go away.
