+ ** Backward incompatibilities
+ 
++*** AC_CHECK_FUNC and similar macros now use function prototypes.
++  AC_CHECK_FUNC and and similar macros now use C declarations with
++  function prototypes, a feature introduced in C89.  The new approach
++  should work better with C23, which removed the non-prototyped K&R
++  style that AC_CHECK_FUNC previously used.  However, this change
++  means Autoconf no longer supports pre-1989 C compilers, as they do
++  not support function prototypes.
++
+ *** Autoconf now requires perl 5.10 (2007) or later.
+   Generated 'configure' scripts continue to run without perl.
