History
Paul Eggert e3fb2efb80 Avoid unnecessary pointer scanning in garbage collection (Bug#10780). 
* alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
(mark_memory): Mark Lisp_Objects only if pointers might hide in
objects, as mark_maybe_pointer will catch them otherwise.
(GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
* s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

README 

This directory contains C header files containing
operating-system-specific definitions.  Each file describes a
particular operating system.  The emacs configuration script edits
../config.h to include the appropriate one of these files, and then
each emacs source file includes config.h.

template.h is a generic template for system descriptions; it describes
the parameters a system file can specify.
