 Just to document the steps take with two configure arguments the failure
 with `/opt/local/bin/gcc-apple-4.2` is:

 {{{
 disk_cache.c: In function 'disk_cache_create':
 disk_cache.c:263: error: 'O_CLOEXEC' undeclared (first use in this
 function)
 disk_cache.c:263: error: (Each undeclared identifier is reported only once
 disk_cache.c:263: error: for each function it appears in.)
 disk_cache.c: In function 'choose_lru_file_matching':
 disk_cache.c:465: warning: implicit declaration of function 'fstatat'
