automake-1.4-p2 doesn't work with autoconf-2.50

[Bruno Haible]

Hi,

Having automake-1.4-p2 and autoconf-2.50 installed, and a configure.in
macro which uses AM_TYPE_PTRDIFF_T, I get an autoconf error because
autoconf-2.50 wants AC_DEFUN arguments to be enclosed by brackets.

Here is a patch for this particular macro.

Can we expect an automake-1.4-p3 release that fixes this?
