 dnl Private macro.
 dnl
 dnl This macro performs embedding of automake initialization
 dnl code into configure script. When automake version 1.14 or
 dnl newer is used at configure script generation time, this
 dnl results in 'subdir-objects' automake option being used.
 dnl When using automake versions older than 1.14 this option
 dnl is not used when generating configure script.
 dnl
 dnl Existence of automake _AM_PROG_CC_C_O m4 private macro
 dnl is used to differentiate automake version 1.14 from older
 dnl ones which lack this macro.
