This is what's new and changed in the c-ares 1.5.3 release:

 o fix adig sample application compilation failure on some systems
 o fix pkg-config reporting of private libraries needed for static linking
 o fallback to gettimeofday when monotonic clock is unavailable at run-time
 o ares_gethostbyname() fallback from AAA to A records with CNAME present
 o allow --enable-largefile and --disable-largefile configurations
 o configure process no longer needs nor checks size of curl_off_t
 o library will now be built with _REENTRANT symbol defined if needed
 o Improved configure detection of number of arguments for getservbyport_r
