They were for handling pointer types. r421074 changed the
transliterations incorrectly - I've reimported the correct versions from
 autoconf 2.59 in r421091:

-define(<<AC_TYPE_NAME>>, translit(sizeof_$2, [a-z ], [A-Z_]))dnl
+define(<<AC_TYPE_NAME>>, translit(sizeof_$2, [a-z *], [A-Z_P]))dnl

-define(<<AC_CV_NAME>>, translit(ac_cv_sizeof_$2, [A-Z ],[a-z_]))dnl
+define(<<AC_CV_NAME>>, translit(ac_cv_sizeof_$2, [ *], [_p]))dnl
