Instead of 2 * LONG_TYPE_SIZE. POINTER_SIZE is believed to be the
correct base on more configurations than LONG_TYPE_SIZE and this
adjustment prevents the need for local patches to compensate on
configurations where the latter is inappropriate, for example
x86_64-mingw.
Tested on x86_64-pc-linux-gnu, committed on trunk
