Autoconf 2.59d (released in 2006) [1] started promoting several macros as not relevant for newer systems anymore, including the `AC_FUNC_MEMCMP`. On some old systems such as SunOS 4.1.3 (EOL in 2003) and NeXT x86 OpenStep (discontinued) the `memcmp` function wasn't present or it didn't work properly. [2] On current systems including at least Solaris 10+ this check is not relevant anymore.
