Issue: app-editors/emacs-18.59-r14 fails to compile (CLANG-STRICTER-SYSTEM).
Discovered on: amd64 (internal ref: clang-stricter_tinderbox)

NOTE:
(CLANG-STRICTER-SYSTEM) in the summary means that the bug was found on a machine that runs clang with stricter mode

This machine uses clang with CFLAGS/CXXFLAGS=-Werror=implicit-function-declaration -Werror=implicit-int -Werror=incompatible-function-pointer-types

Emacs 18 is currently only available on 32 bit platforms, and there are many places where the code assumes that a pointer will fit in an integer.

I am currently working on a 64 bit version which will fix all these problems.
