-dnl @synopsis XIPH_C_FIND_ENDIAN
-dnl
-dnl Determine endian-ness of target processor.
-dnl @version 1.1	Mar 03 2002
-dnl @author Erik de Castro Lopo <erikd@mega-nerd.com>
-dnl
-dnl Majority written from scratch to replace the standard autoconf macro
-dnl AC_C_BIGENDIAN. Only part remaining from the original is the invocation
-dnl of the AC_TRY_RUN macro.
-dnl
-dnl Find endian-ness in the following way:
-dnl    1) Look in <endian.h>.
-dnl    2) If 1) fails, look in <sys/types.h> and <sys/param.h>.
-dnl    3) If 1) and 2) fails and not cross compiling run a test program.
-dnl    4) If 1) and 2) fails and cross compiling then guess based on target.
