AM_TYPE_PTRDIFF_T

[Golubev I. N.]

Version: 1.4-p4

autoconf-2.50 `actypes.m4' defines `AM_TYPE_PTRDIFF_T'.  `aclocal'
fails to detect this and includes `ptrdiff.m4' in `aclocal.m4'.  This
causes conflict of `AC_DEFUN''s during `autoconf' processing.

Q&D solution is commenting out `AC_DEFUN' in `ptrdiff.m4'.  It makes
`aclocal' that macro defn is found, but resulting `aclocal.m4' does
not conflicts with `actypes.m4'.
